+given at compile time, no error handling is needed at runtime, adding two
+numbers cannot fail.
 
 The syntax for types is similar to Java, since it is easy to understand and
 widely used.  The type names are what were used in Vim before, with some
 additions such as "void" and "bool".
 
 
-Compiling functions early ~
+Removing clutter and weirdness ~
 
-Functions are compiled when called or when `:defcompile` is used.  Why not
-compile them early, so that syntax and type errors are reported early?
+Once decided that `:def` functions have different syntax than legacy functions,
+we are free to add improvements to make the code more familiar for users who
+know popular programming languages.  In other words: remove weird things that
+only Vim uses.
 
-The functions can't be compiled right away when encountered, because there may
-be forward references to functions defined later.  Consider defining functions
-A, B and C, where A calls B, B calls C, and C calls A again.  It's impossible
-to reorder the functions to avoid forward references.
+We can also remove clutter, mainly things that were done to make Vim script
+backwards compatible with good old Vi commands.
 
-An alternative would be to first scan through the file to locate items and
-figure out their type, so that forward references are found, and only then
-execute the script and compile the functions.  This means the script has to be
-parsed twice, which is slower, and some conditions at the script level, such
-as checking if a feature is supported, are hard to use.  An attempt was made
-to see if it works, but it turned out to be impossible to make work nicely.
+Examples:
+- Drop `:call` for calling a function and `:eval` for manipulating data.
+- Drop using a leading backslash for line continuation, automatically figure
+  out where an expression ends.
 
-It would be possible to compile all the functions at the end of the script.
-The drawback is that if a function never gets called, the overhead of
-compiling it counts anyway.  Since startup speed is very important, in most
-cases it's better to do it later and accept that syntax and type errors are
-only reported then.  In case these errors should be found early, e.g. when
-testing, the `:defcompile` command will help out.
+However, this does require that some things need to change:
+- Comments start with # instead of ", to avoid confusing them with strings.
+- Ex command ranges need to be prefixed with a colon, to avoid confusion with
+  expressions (single quote can be a string or a mark, "/" can be divide or a
+  search command, etc.).
+
+Goal is to limit the differences.  A good criteria is that when the old syntax
+is used you are very likely to get an error message.

+Another reason why TypeScript can be used as an example for Vim9 script is the

-Classes ~
+Compiling functions early ~
+
+Functions are compiled when called or when `:defcompile` is used.  Why not
+compile them early, so that syntax and type errors are reported early?
+
+The functions can't be compiled right away when encountered, because there may
+be forward references to functions defined later.  Consider defining functions
+A, B and C, where A calls B, B calls C, and C calls A again.  It's impossible
+to reorder the functions to avoid forward references.
+
+An alternative would be to first scan through the file to locate items and
+figure out their type, so that forward references are found, and only then
+execute the script and compile the functions.  This means the script has to be
+parsed twice, which is slower, and some conditions at the script level, such
+as checking if a feature is supported, are hard to use.  An attempt was made
+to see if it works, but it turned out to be impossible to make work nicely.
+
+It would be possible to compile all the functions at the end of the script.
+The drawback is that if a function never gets called, the overhead of
+compiling it counts anyway.  Since startup speed is very important, in most
+cases it's better to do it later and accept that syntax and type errors are
+only reported then.  In case these errors should be found early, e.g. when
+testing, the `:defcompile` command will help out.

+to write code in any language and run it as an external tool, using jobs and

+
+Using an external tool also has disadvantages.  An alternative is to convert
 the tool into Vim script.  For that to be possible without too much
 translation, and keeping the code fast at the same time, the constructs of the
 tool need to be supported.  Since most languages support classes the lack of
 support for classes in Vim is then a problem.
