+// Optimized for instruction cache locality
+//
+// Template class fastcmp used to create more time-efficient str*cmp
+// functions by pre-checking the first character before resorting
+// to calling the underlying string function.  Profiled with a
+// measurable speedup when used in hot code.  Usage is of the form:
+//
+//  fastcmp<strncmp>(str1, str2, len)
+//
+// NB: Does not work for the case insensitive str*cmp functions.
+// NB: Returns boolean, do not use if expecting to check negative value.
+//     Thus not semantically identical to the expected function behavior.
