Please define what kind of correspondence you have in mind, and if you're
going to mention presence of some symbols in Latin alphabet please explain
why that matters at all. To me they're just syntactic items. I don't care
what characters they're made of as long as those are on my keyboard and
the result is easy to read and write (by me).

Let's have a look:
fun (X) -> X end
One more look:
fun (X) -> X; (Y) -> Y end
See? Happy now? :-)
