I'm implementing a CLR <-> Ruby bridge using Managed C++ and the Whidbey
(.NET 2.0 runtime).
There are a lot of novel things in my bridge since I completely avoid usin=
g
Reflection to invoke methods. Instead, I use the lightweight code generatio=
n
(LCG) feature the Whidbey runtime to emit IL instructions on the fly that
form "shims" that call the appropriate CLR object methods.
I'd like to provide an elegant implementation of delegate shimming as well=

Now, you could provide a specific implementation of method_missing to
"capture" the block in the parameter b, as in this example:
def method_missing(name, &b) ...

static VALUE
method_missing(int argc, VALUE *argv, VALUE self)
{
VALUE block = rb_block_given_p() ? rb_block_proc() : Qnil;
...
}

Thanks Nobu! That's exactly what I needed.
