Marshalling delegates

[Nathan Weston]

I can't seem to marshal a delegate. The code below:

class Foo < SimpleDelegate
end

Marshal.dump(Foo.new(nil))

Gives me an error:
TypeError: singleton can't be dumped

The weird thing is that defining _dump or marshal_dump in Foo doesn't
make this problem go away.
Even stranger is that this error suddenly started showing up in code
that used to work... I'm not sure what may haev changed in the interim
(haven't touched the code in a few weeks), except I may have apt-get
updated my ruby installation.

Is there any way I can dump a delegate?

It's a bug in 1.8.0. Soon to be fixed. Thank you.
