It's quite pretty.

But:

1. Removes optional parens for UFCS
2. Syntactic confusion of ref applying to return value and ref applying 
to context. Rules are insufficiently specified.
3. Misses the load mutable-context delegate from const-qualified type case.
4. typeof(dg.ptr), typeof(dg.funcptr) ? (quite obvious what you want, 
but missing)

Also: You will have to change the ABI in order to unify UFCS with 
methods, because the implicit 'this' pointer is passed as the last 
argument for methods IIRC.
