There are surely things I don't understand, but this isn't one of them.

Yep, that's exactly what I was trying to do. A shame you feel it's a bad id=
ea,=20
as it allows code to remain dynamic.

Lazyness is one motivation I won't deny. Another is excessive code - it see=
ms=20
like a complete waste to me. A third is, it won't be forwards compatible. I=
=20
will have to sync the proxies, with whatever methods are added/changed on t=
he=20
original object.
