Does it? I thought the difference between function-scope and
module-scope was compiled in, and everything else boils down to one of
those. Explicit dot notation is different ("ask for Mr Smith, then ask
him where his packages box is, and put this in the box").
Hmm, okay, there's something slightly different with closures. But
it's still unambiguous at compile time.
>>> x=1
>>> def foo(y):
return lambda z: x+y+z
>>> foo(2)(3)
6
>>> import dis
>>> dis.dis(foo(2))
2 0 LOAD_GLOBAL 0 (x)
3 LOAD_DEREF 0 (y)
6 BINARY_ADD
7 LOAD_FAST 0 (z)
10 BINARY_ADD
11 RETURN_VALUE
What multiple namespaces are you talking about, where things have to
get looked up at run time?
