I have a static class that generates unique ID's. The id's are 
hardcoded as ints.

I would like to make this extensible and allow for other integer 
numeric values to be(byte, ulong, etc...).

I can simply make the static class generic without issues.

The problem is the return type of the Get ID function, while 
generic, requires hardcoding the saved ID in a class.

e.g.,

class myclass {
    int ID;
}

while I want ID's type to be that of the uniqueID's type.

e.g.,

class myclass {
    auto ID = uniqueID!T.Get();
}

would make ID a type T (T is defined by the user and known at 
compile time). In another class one might use a different type.

Is anything like this possible? It is purely for convenience as 
I'm trying to avoid having to change the type at two or more 
places.

Try something like this:

class myclass {
    typeof(uniqueID!T.Get()) ID;
    this() {
      ID = uniqueID!T.Get();
    }
}


The typeof(expr...) can be used anywhere a type can be used.

Cool, I'll try it but ran into one problem after making my class 
generic. Yours should work, thanks.
