This is like trying to call an unbound method in Python. What you really
want to be doing is calling chain on an /instance/ of XCall.B, not on the
class object itself.
Also, I'd recommend not clobbering XCall.A and XCall.B with your class
objects, since those are set up to be module objects because they each
have a corresponding .js file. Athena's module system tries to mimick
many aspects of Python's - in this case, XCall corresponds to a package,
XCall.A and XCall.B are modules in that package, and you want to be
defining things like XCall.A.Foo and XCall.B.Bar as attributes of those
