Those would be different errors in Perl:
$ perl -wle 'my $c; $c->foo'
Can't call method "foo" on an undefined value at -e line 1.
$ perl -wle 'sub Foo::stash { return {} }; $s = bless {}, "Foo"; delete
$s->stash->{bar}'
$ perl -wle 'sub Foo::stash { undef }; $s = bless {}, "Foo"; delete
$s->stash->{bar}'
Can't use an undefined value as a HASH reference at -e line 1.
