Yes, I did!

If you don't, you might want consider using syntax-coloring of variables and an editor which highlights/jumps-to error-lines.


Did you really use strict?

Bareword "message" not allowed while "strict subs" in use at /home/lanx/tmp/ line 12.

IMHO barewords can still be lvalue-subs, where your code has perfectly legal syntax.

use strict; use warnings; use JSON; sub message :lvalue { my $a; } message = { result => JSON::false, message => "You messed up", };

runs without problems.

In your case it's a constant bareword.
