Fortunately I've already learned to drive elsewhere and so I can apply
knowledge of how to use some other language's datastructures.

You know, it's rarely ever just a matter of whether the code does what it
should do; it's also a matter of what else can we make it do. Let's call
this the "beyondability factor". In this case this means, how easy it is
to add new features to the code. If you want IEMGUI to stay the same
forever, it doesn't matter; but if you want to make it do things that it
can't do now, you don't want to have to learn C for that, and maybe you
don't want to learn Tcl either.

I don't know when they became useful. I heard that 0.39 was a big boost; I
rewrote IEMGUI in the middle of the 0.37 era; however, I believe that they
were already useful back then, as Frank Barknecht taught them at

Depends on how much "marketing" is put behind the features. Pd doesn't
have enough marketing, the most it knows is people who say sorry for the
spam when they announce their wonderful software. Then for some software
the problems start before that. (e.g.: try to find any executables on

uh, what do you mean?

By having attended PdConvention04 and Piksel05, by reading pd-list and
pd-dev for four years, by founding the #dataflow channel and sitting in it
for five years, and then, by organising twenty-two usergroup meetings that
consist of 2-6 talks each.
