Running Perl 18.2 I was surprised to discover that I can use single
and double quotes as regex delimiters without the 'm' operator.
For example, instead of writing
"/usr/bin/perl" =~ m"/perl"
I can just write
"/usr/bin/perl" =~ "/perl"
Can anyone point me to the documentation indicating which delimiters
don't need the 'm' operator?
you actually are thinking in the wrong direction. the =~ operator causes
its right side to always be a regex unless the s/// or m// or tr/// ops
are seen there. you can even use an expression or sub call or anything
on the right of =~ and it will be parsed as a regex (if no op is there
as i just said).
you can easily check this out with something simple like "/usr/bin/perl"
=~ "/pe" . "rl".
so it isn't the delimiters as you think but the =~ op itself that makes
it a regex.
