<div>Is it possible to figure out the spec of
functions in a compiled module?</div>
<div> </div>
<div>Given a module name I want to be able to
know what is the return type</div>
<div>of a function in that module and what are
the types of the arguments.</div>
<div>But all I know at the moment is the arity
of the function (via module_info).</div>
<div>Is that info lost when compiling? </div>

If the module was compiled with debug info, then you can
call beam_lib:chunks(Module, [abstract_code]) and
traverse the result looking for the spec attributes. </div>

<div class="gmail_extra">I would have expected that the
specs would be listed in the 'attributes' chunk, but it
looks that they aren't. Is there a reason for that?</div>
