Haskell is a great language with a really advanced type-system, although I found its syntax hard to read at times especially as I was exploring the language at first. On the other hand I really liked how Rust syntax was defined in terms of ADTs, Traits & Methods Impls, with type signatures required for functions. Hence I wished for a similar functional language that has such write-style and type concepts, but stripping away the borrow checker, mutations, etc.
