Cameron Kenneth Knight commented on BOO-484:
--------------------------------------------

Check BOO-137 for the solution to the optimization of the for i in range loop.

> Boo's current for loop with range is much slower than C#'s simpler for loop
> If we were to go with Basic's syntax of 
> for <var> = <start> to <end> [step <step>]:
>     <block>
> Which, would give the same result as
> for <var> in range(<start>, <end>[, <step>]):
>     <block>
> but could be made a lot faster.
> I ran a test where I, in C#, iterated through a for loop 1,000,000,000 times, 
> taking 1.75 seconds.
> I then ran a test in Boo that iterated through its for loop using range 
> 1,000,000,000 times, taking 47.58 seconds.
> I don't know if there is another way to make the for-range statement faster, 
> but the way I proposed can cut out the enumerator altogether.
