aren't you just re-compiling the regexp here? 
$_ = qr/$_/;

My goal was to shave off some performance overhead since I have lots of complex regex patterns that need to run fast.

I had thought of just keeping the precompiled patterns in memory (like in %precompiled{$regexkey}), but since the patterns come from a database in the first place, then I have potential staleness if the db gets updated since the Perl app started (mod_perl, btw.)
