So, of course, I had a big demo today and, you guessed it, DrScheme wouldn't
load. I had already rolled back to 4.1.5 because this code doesn't run under
4.2 (or 4.2.1) - we're tracking that down. I reloaded PLT Scheme, etc., but
that didn't work. Eventually, I looked here and saw the problem. Not

These look like good things for me to use for efficiency in the science
collection. Will these these be in the upcoming 4.2.2 release?
I assume that if I use these and introduce a dependency on 4.2.2 or later
that I should also bump the version number of the science collection in
PLaneT

When I was originally thinking about it, I was thinking a macro, too. I like

Done. The PLoT routines (including the extensions in the science collection)

PLplot does have a lot of features, but PLoT doesn't expose all of them and
many others are hidden. You also have access to the underlying plot
