Description Sönke Ludwig 2009-09-14 23:18:24 UTC 
Rebindable.get is an alias for Rebindable.original, which in turn is private:

---
import std.typecons;

class C {}

void main(){
	Rebindable!(const(C)) test;
	const(C) testCopy = test.get;
}
---

test.d(7): Error: struct std.typecons.Rebindable!(const(C)).Rebindable member original is not accessible
test.d(7): Error: struct std.typecons.Rebindable!(const(C)).Rebindable member original is not accessible
Comment 1 Simen Kjaeraas 2010-08-31 07:55:51 UTC 
This is the fix - replace this line(746 in 2.048) in std/typecons.d:
            alias original get;
with this:
            @property
            ref T get( ) {
            return original;
            }

Comment 3 Jonathan M Davis 2010-10-02 19:51:38 UTC 
What's the point of

alias get this;

in the fix? I would have thought that that would conflict with the get property function. It would seem to make it so that get would either give you the type that Rebindable!() holds or Rebindable!() itself which would appear to effectively overload get on the return type.
Comment 4 Andrei Alexandrescu 2010-10-03 12:09:35 UTC 
The alias makes Rebindable!T a near-subtype of T.
