Rust. It has all the good bits of functional programming but basically none of the bad bits.

Good bits:

• Strong type system (though not quite as sophisticated as Haskell or OCaml).
• Map, filter, etc.
• First class functions (though lifetimes can make this a bit awkward)
• Everything is an expression (well most things anyway).

Bad bits:

• "Point free style" and currying. IMO this is really elegant, but also makes code difficult to read very quickly. Not worth the trade-off IMO.
• No brackets/commas on function calls. Again this feels really elegant but in practice it really hurts readability.
• Global type inference. Rust requires explicit types on globals which is much much nicer.
• Custom operators. Again this is clever but unreadable.
• Small communities.
• Poor windows support (not a fundamental thing but it does seem to be an issue in practice for lots of functional languages).
