The Erlang compiler does not currently allow parameterized modules to
be used for parse transforms, but only because of a bad atom_to_list
call. I replaced this with io_lib:format and it seems to work.

I don't want to include this patch as there is no portable way
to use a parameterized module in a compile directive embedded in
a source file.
We might implement another solution for using parameterized modules
as parse transforms later, when/if parameterized modules have become
a support part of the language.
