Should we allow bit-select on/with Bool() type?

**Type of issue**: Feature Request

**Is your feature request related to a problem? Please describe.**

It is nonintuitive what it is supposed to mean if you have a Bool type and do a bit-select on it (which is apparently allowed even if the thing you are bit-selecting with is a boolean!). IN fact it is strange that we allow a Bool to be the selector too.

**Describe the solution you'd like**

It would make more sense if it were a compile or runtime error to do a bitselect on a Bool type or a bitSelect where the selector is a Bool type.

**Describe alternatives you've considered**

Leave things as they are
