[erlang-questions] Record metadata

[Tim Watson]

You'd need the abstract code available and then you can call
dialyzer_utils:get_record_and_type_info/1 which returns a dict
containing the type information. You can then pass this dict to
various functions in the erl_types module to get back information
about type specs.

If you don't want to rely on dialyzer at runtime, you'll need to
copy-paste the code from dialyzer_utils AFAICT. Also the erl_types
module is part of hipe.
