in thread Perl Python Partial Polyglot

Assuming the offending code looks something like this:

my $hashref = { .... };
my $keysCount = keys $hashref;

[download]

Then add a dereference:

my $keysCount = keys ${ $hashref };

[download]

Or just:

my $keysCount = keys $$hashref;

    Thanks...what ended up working was changing: 
    perl(split/\n/,(keys(${{}))[0])

    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!?

      Nevermind, thought this was in reply to my reply.

      And yet, somehow, my post prompted the OP to both find his own solution and post code demonstrating the original problem. Clever huh?

        Even knowing your high self-esteem I am amazed that you would claim that your erroneous contribution was so "clever" that it deserves the credit here. Most people would have said "oops."
