I've added a DIP for this
(https://github.com/dlang/DIPs/pull/61).
At first I first thought that all we needed was to add
semantics to take the address of a UFCS-style call, but after
messing around with your example I realized that delegates are
not ABI-compatible with functions that take the delegate ptr as
the first parameter. You mentioned that the problem was with
the parameter order and that this should work with extern(C)
functions and I think you're right.
The new DIP proposes the addition of "Extension Methods" which
are functions that are ABI-compatible with delegates. You
define an extension method by naming the first parameter "this":
[...]
Scratch the "Extension Methods" idea. I've found a more
generalized way to do the same thing. I'm calling it
"Delegateable Functions" (https://github.com/dlang/DIPs/pull/61).
