I want to switch off the significance of special characters when matching an expression in perl, i.e. I have a line that says:-
if (@_[0] =~ /$a/i)
(isn't perl horrible!) and I want a '.' in the $a to be actually matched. I can't easily escape the '.' with a '' because the $a is also used as a filename and if I put the '' I get a filename with a '' in it as well which I don't want.
All I actually want is a case insensitive string comparison with no characters having any special meaning at all.
