Re(3): Regex Capturing: Is this a bug or a feature?

[Dog and Pony]

It has bitten me too, and I bet some other people too. I know about it know, and it is ok, but what really lacks is documentation about it.

I seem to recall that it triggers some awkvardness in solutions too, at times, as just because a regexp matches, it may not actually fill all of the $n variables, and old values may still be there, and that makes checking harder. I would have to get back on that with a real example though, in case it is my memory that fools me. :)

I believe you're correct. I tried to verify my recollection and came up with something even stranger.

#!/usr/bin/perl
# 5.6.1
use strict;
use warnings;
my @values = qw ( one  var.1 test);
getsymbolval(@values);

#################################################
sub getsymbolval{
    my @syms = @_;
    foreach my $symbol (@syms){
        $symbol=~m/(\w+)(\.)?(\d+)/;
        print "symbol: $symbol\t\$1: $1\t\$2:$2\n";
        my ($ts,$te) = ($1,$2);
    }
    wantarray ? @syms : $syms[0];
}

__END__

Output follows (minus uninitilized warnings): What's up with just 'v' being in the regex?
symbol: one $1: $2:
symbol: var.1 $1: var $2:.
symbol: test $1: v $2:
Very odd.
