I've not had any problems with JSON that has dollar signs in keys in any of the common Perl JSON implementations; such things are pretty common, like in the JSON Schema spec.

Pretty sure you're doing something weird and the issue isn't in the JSON modules. Please post full code of something that behaves unexpectedly.

This thing which you posted should work:

$decoded_json->{feed}->{updated}->{'$t'};
