Perhaps it isn't all that difficult;
For instance, a "local:" declaration could be treated as if it were "def
function()" with an immediately succeeding call as far as the interpreter
is concerned. That buys the scoping for (nearly) free.
We write...
local:
for MyVal in range(0,10)
pass
...interpreter codes that, out of sight, as:
def ghost_func_0000001():
for MyVal in range(0,10)
pass
ghost_func_0000001()
Might take a bit of fiddling to make sure return and yield were appropriate
[requiring an actual enclosing def function():], but other than that, it's
basically the same idea -- provides scoping, making it easier for us to
code, debug, and document, while significantly decreasing the likelihood of
variable collisions.
