No bugs if you ask me. A couple of examples of the correct way to properly use single quotes are {-delim => '/\\'} or {-delim => '\/'}/ or {-delim => '\\/'}.

How the Regex module interprets this I don't know, probably a quotemeta or something like that.

The point is that in:

print "P1 has path\n" if ($P1 =~ /$RE{delimited}{ -delim => '\\\/' }/ );

the quoted string becomes

-delim => '\/' ;

In:

print "P1 has path\n" if ($P1 =~ /$RE{delimited}{ -delim => '\/' }/ );

The quoted string becomes:

-delim => '/' ;

This is because the \ is treated as an escape character beteween //.

It is always tedious in Perl how mistakes like this slip in. For example take a quick look at swl's example, I think that the '\' characters is specified twice in:

print $RE{delimited}{-delim => '[\\\/]'};

I even hope that I did not make any mistakes myself right now :P
