True, that's basically the same approach (i.e. doing my own
formatting) I wound up with.  Though usually not with printf because
the whole type unsafe thing.  But I did waste a fair amount of time
over a number of years before realizing that custom formatting is
almost always worth it, even for one off Debug.traces, and I wound up
with my own trace library for the same reason.

See, I told you I'm no good at this scienterrific physical faddle!  I
