G'day ll001,

I see that ++aitap has identified your problem.

Seeing your usage of $regexStr, I was wondering if you were aware that qr{...} does not return a string per se. It actually returns a Regexp object. When stringified, this is overloaded to produce something you may not have expected. 

$ perl -e 'my $regexStr = qr{[0-9]+};
print "$regexStr\n";
print ref($regexStr), "\n";
'
(?^:[0-9]+)
Regexp

See perlop - Regexp Quote-Like Operators for details.
