How do you indicate the particular scope to which foo will be bound (there
can be many lexically enclosing function definitions)? Using my example
again:
def outer(a):
x = a
def inner(a):
x = 42
def innermost(r):
global x from def # <--- your notation
x = r
print " inner, x @ start:", x
innermost(random.random())
print " inner, x @ end:", x
print "outer, x @ start:", x
inner(a)
print "outer, x @ end:", x
how do you tell Python that x inside innermost is to be associated with the
x in inner or the x in outer?
