Re^3: I THOUGHT I'd finally understood genex

[AnomalousMonk]

I thought by using a string at the top for the expression I was making it easier to read.

Even without the confounding  m/ / pieces in the string, it's almost never a good idea to use either a single- or double-quoted string to define a regex if you can avoid it; many subtle pitfalls lurk there. Use the  qr// operator instead; see Regexp Quote-Like Operators in perlop.
