That's a shame.  Perl introduced the syntax and I originally wrote the
Zsh =~ code to use the existing zsh/pcre module.  It was only
reluctantly that I added the zsh/regex module so that =~ could match
Bash's behavior by default, because folks felt that compatibility with
Bash was more important than being powerful.  Almost everything I do
with =~ in Zsh uses REMATCH_PCRE.

I'll have to hunt down that thread and see what I can do about that.
