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

    [ http://jira.codehaus.org/browse/BOO-137?page=comments#action_47424 ] 

Cameron Kenneth Knight commented on BOO-137:
--------------------------------------------

The above comment refers to the attached file "OptimizeIterationStatements.cs"

now the iterators run just as fast as C#'s equivalents, while keeping Boo's 
shiny syntax.

> 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
