Thanks for that - I appreciate your comments. I'll
confess to being a bit of a map abuser - I
tend to use it whenever I need to create a list or
hash, although I do try to comment serious abuse
Your QA point is a good one too - I work for a well
known and well established website built almost entirely
with perl and going through some old code I've found
all sorts of mistakes - now I'm trying to import all
the millions of lines of bad data it's created into
a replacement system.
Most of the mistakes are due to
bad assumptions, often using regexps to match parts of
strings out, but never testing whether the match was
successful and getting a previous value of $1 or something.
I sometimes wish that there were much more warnings about
that sort of thing.
