[question] Bit operations for Expr

[npatsakula]

Hello there!

Is it possible to use bit operations (or, and, left/right shift) with halide-haskell?

[twesterhout]

Hello @npatsakula ! Bitwise operations are indeed missing (there are boolean or and and though). I'm a bit conflicted about the interface... For instance, in halide-haskell the type of shift would be Expr a -> Expr Int32 -> Expr a whereas in base it is a -> Int -> a. I need to think a bit how to best expose the bitwise operations with the syntax that is familiar to Haskellers, but without clashing with Prelude too much.

Personally I don't have any prejudgement about overlapping with Prelude: you can use qualified import and use functions with familiar names. I'd be glad if you tell me more about problem here.

Also I need to mention that Accelerate using shift function name as well.
