Ahem, both of those snippets are non-working: 

$ perl -Mstrict -wE 'my $h = {foo=>"bar"}; my $c = keys ${$h};'

Experimental keys on scalar is now forbidden at -e line 1.
Type of arg 1 to keys must be hash or array (not scalar dereference) a
+t -e line 1, near "};"
Execution of -e aborted due to compilation errors.

$ perl -Mstrict -wE 'my $h = {foo=>"bar"}; my $c = keys $$h;'

... presumably you meant: 
$ perl -Mstrict -wE 'my $h = {foo=>"bar"}; my $c = keys %{$h};'

[download]
$ perl -Mstrict -wE 'my $h = {foo=>"bar"}; my $c = keys %$h;'

Aside: how odd that your post continues to garner upvotes (rep up three since I posted this); you don't suppose people vote based on the author's reputation without really reading the post, do you!?


The way forward always starts with a minimal test.
