Nope, but even the most simple manual test should find it pretty quick.

Don't you ever test your code ???

It does. Just try to run your code, and you'll have a nice traceback.
Unless of course 'foo' is rebound in module two to another callable
expecting only two parameters...

Perhaps do they rely more on testing and less on the compiler ? FWIW,
I've seen my share of bugs in declarativly statically typed languages,
and most of them were way nastier (and way less obvious) than the above one.
> How you catch these types of errors?
Just like any other type of errors : testing, testing, and then add some
more tests.
