Similar drawback: you can't get the function value of a method. And if 
you allow this somehow, you basically just have two different namespaces 
for methods and properties, which will slow down lookup for one of those.

But I admit that providing properties *and* methods for a userdata feels 
a bit clumsy. I usually set an index metamethod with the method table as 
an upvalue, and check the method table first and then look for 
properties in the userdata. Maybe we could add an API function to 
lauxlib to help doing something like this ...
