[CM] When does a let get created?

[Woody Douglass]

Yeah, creating a let explicitly like that works -- i'm at a point where
i can move on now, i'm just trying to figure out why i saw the aliasing
from my original implementation -- why doesn't returning the lambda's
implicit let work in the way that i expected?

Thanks,
Woody
