Suggestions for functions:

Perl-like 'grep' to return a new array containing all elements for which func() returns true.

Perl-like 'map' to return a new array containing return values of func() for each element. (array_walk is nearly this, I think)

regcomp()-like function which will tell if a user-supplied regexp is valid and if not, why not.

added (except for regcomp(), but you'll see a warning if eregi is passed an invalid regex).
