[ID 20000307.006] $1, $2 and the '..' operator

This is a bug report for perl from ajh@doughboy.rtk.com,
generated with the help of perlbug 1.26 running under perl 5.00502.


-----------------------------------------------------------------
[Please enter your report here]

It looks like $<digit> vars don't appear to interact cleanly
with the '..' operator.  For example, this script:

    #!/usr/bin/perl -w

    use strict;

    my $foo = "A-C";
    if ($foo =~ s/^(\w+)-(\w+)//) {
        print join(",", $1 .. $2), "\n";
    }

    my $bar = "A-C";
    if ($bar =~ s/^(\w+)-(\w+)//) {
        my $baz = $1 . $2;
        print join(",", $1 .. $2), "\n";
    }

gives this output on my system:

    Argument "A" isn't numeric in flop at ./bug.pl line 6.
    Argument "C" isn't numeric in flop at ./bug.pl line 6.
    Argument "A" isn't numeric in flop at ./bug.pl line 6.
    Argument "C" isn't numeric in flop at ./bug.pl line 6.
    0
    A,B,C

Note that the script gives the expected results on line 13.
