Fellow mongers:
Can anyone think why /e might be a bad idea to suggest for addition to
the qr// operator?
I found myself doing something like this, the other day:
my @days = qw( Sun Mon Tue Wed Thu Fri Sat );
my $days_re = qr/join '|', @days/e;
And I was startled to discover that qr doesn't have a /e flag.
Granted, it has only ever been in the substitution part of s///, but
this seems pretty straightforward. There are obvious workarounds:
my $days_re = do { my $tmp = join '|', @days; qr/$tmp/ };
Or, in this particular case, something almost as ugly:
my $days_re = do { local $" = '|'; qr/@days/ };
Still, it seems that /e might be entirely useful on qr//. Anyone have
examples or counter-examples that come to mind?
