[ID 20000125.006] strict.pm not strict enough

[Greg Bacon <gbacon@itsc.uah.edu>]

This is a bug report for perl from gbacon@ruby.itsc.uah.edu,
generated with the help of perlbug 1.27 running under perl 5.00563.


-----------------------------------------------------------------

A post on clpmisc today contained something like

    #! /usr/bin/perl -w
    use strict

    $, = ' '; # set output field separator
    $\ = "\n"; # set output record separator

    $foo = 42;

That shouldn't compile, right?  Notice that there's no comma after
C<use strict>.  The code above is equivalent to C<use strict ' '>
which fails to enable any stricture!  It's because of the following
line in &strict::bits:

    foreach my $s (@_){ $bits |= $bitmask{$s} || 0; };

IOW, C<use strict 'foobletch';> is a nop.  I can see how one might
construe this as a backward compatibility feature, but if a programmer
casts a spell of protection, Perl ought to thump back for using false
magic.

This is also the case for 5.00503.
