        Looks very interesting...will have to peruse it...
I'm starting to use eval more often -- generally haven't because
I thought it to be slow, but realistically, and as the article states,
with hard-timings, it's faster than expression in a sub-process...

        That could lead to much more flexibility (besides benefit of speed).
