Problem with cyclic dependencies between types and functions from different files in F?

As mentioned in the comments, there is no way to split functions (or types) with cyclic dependencies between multiple files. Signature files are useful mainly for documentation purposes, so they won't help It is hard to give some advice without knowing what exactly the dependencies are. However, it may be possible to refactor some part of the implementation using functions or interfaces.

For example, if you have: let rec process1 (a:T1) = match a with | Leaf -> 0 | T2Thing(b) -> process2 be and process2 (b:T2) = match be with | T1Thing(a) -> process1 a You can modify the function process1 to take the second function as argument. This makes it possible to split the implementation between two files because they are no longer mutually recursive: File1. Fs let process1 (a:T1) process2 = match a with | Leaf -> 0 | T2Thing(b) -> process2 be // File2.

Fs let rec process2 (b:T2) = match be with | T1Thing(a) -> process1 a process2 If you can find some more clear structure - e.g. Two blocks of functions that contain logically related functions and need to access each other, then you can also define an interface. This doesn't make much sense for the example with just two functions, but it would look like this: type IProcess2 = abstract Process : T2 -> int let process1 (a:T1) (process2:IProcess2) = match a with | Leaf -> 0 | T2Thing(b) -> process2. Process be let rec process2 (b:T2) = let process2i = { new IProcess2 with member x.

Process(a) = process2 a } match be with | T1Thing(a) -> process1 a process2i Anyway, these are just some general techniques. It is difficult to give a more precise advice without knowing more about the types you're working in. If you could share more details, perhaps we could find a way to avoid some of the recursive references.

Be * 2 - 1 : 0 + 1) * be else 2". In this example there are several cyclic dependencies: c can be an Expression, array a can have several predicates, with index also calculated as Expression, parentheses in arithmetic calculations are also use recursion, etc.Btw, nice book - it helps me a lot in understanding F# – Vitaliy Mar 23 at 15:13.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
