Purity isn't in contrast with pragmatism; what Haskellers refer to as purity is referential transparency.

You can still do this kind of work in Haskell as well. It is a great imperative language.

Though as someone who has written assembler compilers in Common Lisp... it's felt relatively easy to do in CL. I've only heard people talk about writing control software for drones from Haskell. I have no idea how one would do that in practice though.
