The helpfile mentions that a new InterpEnv is returned, but I agree
with you that this isn't how a class should behave now that I think
about it. Here is part of the problem with the change above:
a = InterplXYC([[-1, 1, \sin], [0, 2, \lin], [1, 0]]);
a.postcs; // slots are definitely for InterplEnv, but it says XYC
I'll work on this a bit to make sure code isn't broken. Probably the
answer is to have creation methods of InterplEnv for newXYC and
newPairs that take the arguments that InterplXYC and InterplPairs
takes... Then, remove the helpfiles and references in the helpfiles
for InterplXYC and InterplPairs.

It allows this:
a = [1, 2, \sin, 50, 100, \lin];
a.flat.clump(3).flop
a.flop
where a single array of XY and curves are simply passed in. I don't
mention anywhere that this can happen, so I think it can change (I
have to look over some old code of mine though... this is from
thinking about these envs like I would use them in CommonMusic and
LISP).

I'll change it... makes sense (avoids creation of a new Object).
Thanks!

“Every composer – at all times and in all cases – gives his own
interpretation of how modern society is structured: whether actively
or passively, consciously or unconsciously, he makes choices in this
regard. He may be conservative or he may subject himself to continual
renewal; or he may strive for a revolutionary, historical or social
palingenesis." - Luigi Nono
