How to call methods from the constructor in F #

Question

I know this question , but it seems the crawler is satisfied with the answer to another question (how to overload the constructor)

I have a class that acts as an extended memoizer around a mutable class, so that I can treat it as immutable from the outside:

type Wrapper(args) = let tool = new MutableTool() tool.Init(args) //<--"Unexpected identifier in definition" let lookupTable = //create lookup using tool here member this.Lookup(s) = //callers use lookupTable here 

I cannot figure out how to call the Init method on a "tool". What am I missing?

Answer 2

 type Foo(args) = let x = new Whatever() do x.Bar() member ....
