Since `&opt = value` is now assigning a value to option "opt", ":&" cannot be
used to repeat a `:substitute` command.
+For an unpack assignment the underscore can be used to ignore a list item,

+ [a, _, c] = theList
+ [a, b; _] = longList

+That is because the type needs to be inferred from the list item type, which
