perl-ish regexps?

Yes, I'm back again. Be afraid, be very afraid..

I was wondering if anyone would be willing/capable of implementing perl-
like regexps, in a function called regex() or something?
Yes, I know, perl and its regexps look like line noise, but typing
result =3D regex({^\(d).?\1$}, myVar)

(and I use {} instead of // as in perl  {RE} vs. /RE/)

is rather easier than the euphoria equivalent of.. well... whatever.
(The regexp in question would find a 'word' that starts with a digit and
possibly has a string of characters after it, and ends with the same digit).=

You could make the function either return the closest match, or return all
the matches if the user so desires (result should be an object?)

This could make things easier for the database (and such) inclined.

And adding the substitute function would be totally brilliant, so removing,
for example, excessive whitespace from scripts, formatting text to whatever
you want and such would be so much easier.

sequence x

x =3D "spaces a            plenty"

x =3D subst({\s+}, {\s}, x)

x whould be "spaces a plenty" (unless I messed up the regexp, which of
course is highly possible).

x =3D "m5439'.e5588/#s...-*''s009989/&a785784g=B4654677,,.^^=A8=A8=A8~~e"

x =3D subst({[^a-zA-Z]}, {}, x)

x would amount to "message" (ooh! Aaaah! Uuuuuuh!)




Any thoughts on this?
