in the expression

src<- source 0

src becomes of type source int, according to the compiler, but it is
not clear how the typing happens.

The situation is exactly the same as in Haskell. The key is that [src <- source 0] by itself is not an expression. Rather, the holistic form [x <- e1; e2] is shorthand for [bind e1 (fn x => e2)].
