[jira] Commented: (BOO-137) optimize for item in array construct

    [ http://jira.codehaus.org/browse/BOO-137?page=comments#action_47554 ] 

Rodrigo B. de Oliveira commented on BOO-137:
--------------------------------------------

Please make sure that all tests currently in the repository pass (I've just 
added some test cases regarding range runtime behavior).

Another thing, all the files in the boo code base must have the following 
header:

> The current progress in the generators front required deoptimizing the 
> handling of "for item in array" constructs.
> for item in array:
>     pass
> should expand to:
> i = 0
> while i < len(array):
>     item = array[i]
>     ++i
> instead of today's:
> iterator = array.GetEnumerator()
> while iterator.MoveNext():
>      item = iterator.Current
