This is a bug report for perl from jhi@lyta.hut.fi,
generated with the help of perlbug 1.34 running under perl v5.8.0.


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

Bleadperl or 5.8.0:

$ ./perl -e 'local ${"FOO"}=1'
Can't localize through a reference at -e line 1.
$ 

What reference where?

perldiag says:

=item Can't localize through a reference

(F) You said something like C<local $$ref>, which Perl can't currently
handle, because when it goes to restore the old value of whatever $ref
pointed to after the scope of the local() is finished, it can't be sure
that $ref will still be a reference.

But I still fail to see a reference in there.  To be honest, I had
originally something more that "FOO" in between the {}, I had "\cFOO".
But still completely compiletime, nothing naughty like "FOO$BAR".
