Perfect! Thanks Rich. I actually read over this thread before but
completely forgot about it (this group has really picked up steam over
the last couple of months). Next time I'll try searching the group
more, rather than adding more noise.
However, I will reiterate the last threads conclusion. #^ is not a
macro for with-meta. That is what I think tripped me up. I may still
not understand the full power of #^, but as long as I remember it's
not sugar for with-meta than I should at least avoid shooting myself
in the foot.
