Yep, that too! I think even applications could exist as 'things': get
a list of applications, query an application for its modules.

<sidenote> There is no such thing in Erlang as a module, just a name
in the documentation and the attribute with the said name. Otherwise
one does handle and refer to beam files. There should be an API to
handle modules that hides the underlying beam_lib, as an example.
