[curry] Re: Haskell compatibility

231 extensions as of GHC 8.6.5. (Some people are using 8.8 in production
already, and 8.10 is available but not stable yet.)

Of course, any Turing-complete language can do anything any other can.
There exists code that uses things like GADTs without really needing to.
But then again there are programs that would be really verbose and
confusing without the extensions.
