[chuck-users] problems with chubgraphs

Makes sense as that is one of the members they all have in common; I'd
like to know about situations where it didn't.

Likely. Barring structural evidence it seems to me that ChucK's type
system has particular issues with objects that have multiple types.
"foo" might be a object, a UGen, a Filter and a LPF, all at the same
time. We should be able to -legally- cast it up and down that
hierarchy but this sometimes goes wrong, particularly when as in your
example, it is also a element of a array.

That's gut-feeling based on experience, it might be way off in the
face of a formal analysis (TODO :-) )

Yours,
Kas.
