Your version doesn't get arrays right, however.
Here's a Perl/Python/Ruby version below. It should be extendable for
other languages; feedback and additions appreciated:
Note that usage has been changed to --dump=(perl|python|ruby)
I may add key_suffix to lang_dump just to be consistent with pairings,
but array_start seems to handle all cases of it and it would be
redundant...
