[erlang-questions] metaprogramming with -spec

[semmit mondo]

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