No they don't. "begin with either is or to and a lowercase letter", 
meaning (is|to)[a-z].*, just as Morten wrote. is_.* doesn't fall into 
this category. The underscore exemption is so that users can write their 
own is_file(), is_whatever() str_replace() and such. Some thought has 
gone into the standard.

Also, note that we don't include <ctype.h>, and the reasons to stay out 
of its namespace are:

a. potential for confusion (different semantics), and
b. broken system headers.
