Are you using Dialyzer to check types? The Erlang compiler itself does
not perform typechecking. You can run Dialyzer (included with OTP) on
your source code like this:
$ dialyzer --src <source code directory>
or, if you compile your code with debugging enabled, you can run it like
$ dialyzer <object file directory>
In addition to inferring types, Dialyzer will check that code adheres to
-spec declarations, and it will warn about unexported types.
Note that you have to run Dialyzer on *all* your modules, as it only sees
the modules you tell it about, and those whose specifications have been
explicitly stored in its "PLT" database (by default erts, kernel, and
