looking at:
x = 'global'
def f():
 def init():
 global x in f
 x = 'in f'
 def g():
 print x
 init()
 g()
I don't really know whether to call explicit or implicit the fact that x in g
is not the global one. And contrast with
x = 'global'
def f():
 x = 0
 def init():
 global x
 x = 'in f'
 def g():
 print x
 init()
 g()
or consider
x = 'global'
def f():
 global x
 def init():
 global x in f
 x = 'in f'
 def g():
 print x
 init()
 g()
