This is a bug report for perl from zefram [at] fysh,
generated with the help of perlbug 1.36 running under perl 5.10.0.
-----------------------------------------------------------------
[Please enter your report here]
Investigating around a B::Deparse problem that Nicholas just reported,
I found this:
$ perl -MO=Deparse -e 'my $pi :shared = 4'
use attributes ();
('attributes'->import('main', \$pi, 'shared'), my $pi) = 4;
-e syntax OK
Note that \$pi is referenced before "my $pi" comes into scope, so the
reference is wrong. Also, the attempt at a comma operator on the LHS
of assignment ends up doing a list assignment, and attempting to assign
4 to the return value of the ->import. Need cleverer code generation.
[Please do not change anything below this line]
