Heh heh ... thwack away! ;)
"... is it simply an issue of pre-emptive maintenance
coding headache prevention?"
I think so. What if you suddenly decide that the string you
need to match needs to be dynamic? You forget to remove the
modifer and possibly spend a lot of time trying
to find the bug when your regex stops matching. Here is
some code to demonstrate:
@data = qw(foo bar baz qux);
print "search: ";
chomp ($in = <STDIN>);
last unless $in;
print $_,$/ for grep /\Q$in\E/o, @data;
I figure why bother with such premature optimizations if
they have the potential to bite.
