Re: [Python-Dev] Doubt about closure/function generation in bytecode

2013-07-15 Thread Benjamin Peterson 
2013/7/12 Andrea Griffini agr...@tin.it:
 Is there any semantic difference between

 BUILD_TUPLE 0
 LOAD_CONST code object ... 
 MAKE_CLOSURE 0

 and

 LOAD_CONST code object ...
 MAKE_FUNCTION 0

 ?

 In other words is there any difference between a function and a closure that
 doesn't capture anything? Is it just a speed optimization for a common case?

It probably has more to do with the fact that nested scopes with added
much later in Python's history than functions.
