By "local scope", do you mean as in "local variable"? I.e. you do

def foo():
  def bar()
    pass
  myext.somefunc()

and then you want the somefunc, which is implemented in C, to access
bar??? That isn't supported. It is possible, but you will have to read
the source yourself to find out how to do it.

Instead, I recommend that you do

  myext.somefunc(bar)

instead, i.e. passing the callable as an argument to the extension.
