Yeah, I'm aware of what's he's riffing off (note that Greenspun's had nothing to do with Haskell). It's still an annoying attitude to have toward any new functional language that happens to share a syntax with Haskell.

Is that the gp's attitude toward PureScript, for example? Or Idris?

If that's the case, it must be nice/"interesting"/boring having found a "forever language". Look forward to seeing how that's going for him in 2030.
