Probably not. See below.

I'm unaware of these. Thanks for the pointer.

Haskell is already a stretch. Doing things like this:

a <- (b `and`) =<< not c

Is just never going to work.

Keeping it in ANF:

nc <- not c

a <- b `and` nc

Is easier to explain, but it is very hard to justify why you can only 
put the result of a single operation in a variable, and why sometimes it 
is "let" and other times it is that arrow.

Basically I'm asking people to give up expressions while they work just 
fine in C or Verilog. It's a step down. I really don't blame them.
