perldiag is still correct, because this error was only removed in some
cases. Perl 5.8.1 allows localization through a symbolic reference, but
not a hard one :
$ bleadperl -le '$x="a";local $$x=2;print$a,$$x'
22
$ bleadperl -le '$x=\"a";local $$x=2;print$$x'
Can't localize through a reference at -e line 1.
