Subject: Passing a proc as block to a method from a C extension

Hi,

I am looking for a way to do the equivalent of the following ruby function  
in a C extension:

def foo(my_proc)
     bar(&my_proc)
end

(and it should also work if bar is instance_eval or module_eval)

I couldn't find a way to do this, the only idea I have is to do something  
like:

def foo(my_proc)
     bar { |arg| my_proc.call(arg) }
end

This can be done using rb_iterate, but it obviously doesn't work with  
instance_eval and module_eval.

Any ideas?

Dominik
