To me, though, block_eval doesn't signal the switching of self.  Not
that I have any brilliant ideas here....  Something with "context" in
it, maybe?  instance_context?  context_eval?  context_adopt?  Is there
likely to be something parallel for module_eval?  

I'm also trying to picture exactly what the syntax would be.  I think
I'm not quite getting it.  Can someone write one or two examples of
ways you would use this?
