@5150cec1 @4c9dfcc3 Haskell isn't complex.  GHC is.  The type inference is sophisticated, but not complex.  The syntax / grammar is actually very small.  The core libraries defined in the report are also small.  I think the most complex thing in the report are the rules around how foreign imports interact with the core library, and that can be avoided.  Haskell 98 didn't have a standard FFI.

Haskell is many things (hard, frustrating, theoretical, awkward, etc.), but not complex.
