+ * results of say isalpha('A') wrong for what ever retarded locale
+ * is used. Simalerly these are also implemented inefficently on
+ * some toolchains and end up becoming actual library calls. Perhaps
+ * this is why tools like yacc provide their own? Regardless implementing
+ * these as functions is equally as silly, the call overhead is not
+ * justified when this could happen on every character from an input
+ * stream. We provide our own as macros for absolute inlinability.
