Those functional languages don't have function overloading or named arguments. The type inference in Crystal works very differently. The type of a method can only be computed from explicit calls to it. In those functional languages the type can be computed independent of a call because it's trivial to do so if a function name always refers to a single entity. |

Scala has both, F# too (though function overloading is possible, I think it's not idiomatic), OCaml has named arguments, Haskell has overloading.
