hello! i worked there for 2 years. yes it is a fork called Mu, no it is not not lazy. The Mu Core team are devout Haskellers so don't be too quick to dismiss them as abandoning Haskell's core values.

Thanks for the clarification! I never thought they were not devout Haskellers, but I do always wonder about projects that fork a more standard thing for internal use ending up as poorly maintained legacy software.
They didn't fork GHC. They wrote a new Haskell compiler to target a pre-existing runtime that existed inside the bank. For various reasons related to the runtime that meant the language had to be strict. Mu's creation was, in fact, a step away from legacy.
