Thanks, sorry to provoke an RTFM. I've been out of touch and I don't think
perlhack(1) was there the last time I looked.

My new bleadperl (DEVEL11741) has the bug still.
So far, I've only heard from people who don't see the bug :-(

I don't have bleadperl anywhere except on Linux/686, but Activestate 626 on W98
also shows it up.

--- Test program
#! /usr/local/src/bleadperl/perl
    %actions = (
        'x' => sub {
                    eval $_[1];


print &{$actions{'x'}}('', '$bar' ) ;
