improve for loop #151

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

l1=[1,2,3]
l2=[(4,5),(6,7)]

for i in l1:
    print(i)
for i in l2:
    print(i[0],i[1])

What is the expected output? What do you see instead?

Shedskin return:
*WARNING* petle.py: variable 'i' has dynamic (sub)type: {int, tuple2}
*WARNING* petle.py:5: expression has dynamic (sub)type: {int, tuple2}

What version of the product are you using? On what operating system?
Debian, Shedskin 0.8

Please provide any additional information below.

Variable 'i' is in 2 different loops. I suggest in this case Shedskin should 
see 2 different 'i' variables instead one.

thanks! :) I agree some 'dynamic' cases such as this could actually be 
supported, but imo it's not worth the complication at this point, and it's 
usually very easy to work around the problem..
