Why does nobody seem to anchor regexps? I have seen so many documentation
examples now which suggest that something like

    raise "Invalid data" unless /[A-Za-z0-9]+/ =~ data

is a good example of data validation :-(

It would be a drift away from Perl, but I wonder if regexps should be
anchored by default, and you'd have to add a flag to them to make them
unanchored...

Sorry, just my gripe of the day.

Brian.
