Both Lua and Python are great suggestions. But avoid the issue
of fixing [shell]. It has been problematic for a long time and
this is another opportunity to discover how to fix it, or
deprecate/remove it altogether.
I think there's something to be said for all Pd distros _not_
including [shell] for obvious reasons. If users want to open
that door it should be an informed decision. That would happen
if they could only use PyExt and PdLua. [shell] is very buggy,
has it's day finally come to be fixed or dropped?
