F# question

Well, the order in which files are presented to the compiler and the order of declarations within a file are significant in F# because everything needs to be declared before it can be used.

As far as I'm aware, F# doesn't support any kind of forward declaration so that would rule out having interdependent classes (i.e. classes which reference one another) in different files.

However, you could do something like this if they were defined in the same file:

type firstType =

| T1 of secondType

//................

and secondType =

| T1 of firstType

//................
