The maximum arity N of a function type that's implemented
as a trait scala.FunctionN. Functions of higher arity are possible,
but are mapped in erasure to functions taking a single parameter of type
Object[].
The limit 22 is chosen for Scala2x interop. It could be something
else without affecting the set of programs that can be compiled.
