Thanks Chas., that's interesting! Here's my summary of what I've learnt
from this:
1. The regex
$foo =~ "\Asome string\Z"
is equivalent to
$bar = "\Asome string\Z"; # ends up as 'Asome stringB' with a warning
$foo =~ /$bar/;
i.e evaluate the string first and then stick it into the regex delimi
Be careful, it isn't actually a regex; it is a string that will be compiled
to a regex. You can see one difference here:
#!/usr/bin/perl
use v5.20;
use warnings;
say "string matches:";
for my $s ("foo", "AfooZ") {
say "\t$s: ", $s =~ "\Afoo\Z" ? "true" : "false";
}
say "regex matches:";
for my
Thanks Uri!

For example, instead of writing

I can just write

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 indicatin
