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()
