I agree completely. I'll fix it.

Thank you, it does mean a lot to me.

The := used to declare stuff, has to be different from =, which has no
special meaning for the language. I still don't know whether to use it
for equality (instead of '==' like in c languages) or for assignment
(instead of <-, like in some other languages). In the future, optional
type information could go between the ':' and the '='.

I can't see the page you liked to, it looks like the server is having trouble:
Fatal error: Out of memory (allocated 5242880) (tried to allocate
1245184 bytes) in

Anyway, multi line function are as easy as:
def f(x) := {
  val y := x + 1
  y * 2
}
The function returns the result of the last expression.
