Definitely.  I think breaking the code down is fine (I might avoid
adding to Kernel, but that's another story :-)  I was chiming in more
on some of the stuff Erik raised by way of context.  And of course
there's a long history of the dividing of "regular" from "meta" in
Ruby, and a fairly long history of my skepticism of it.  Erik's post
just put me in mind of the whole thing.
