hmmmmm....what kind of performance are we talking about here? just looking
at the simple cases where i want to do this, it looks like an easy
half-dozen invocations of the block. in the more common, complex cases, it
looks like there could easily be hundreds or thousands of invocations.
that's why i'd like to do the compiling up front.
