Iterators for N = 0 iterations

[dariosanfilippo]

Hello again.

Following my last discussion on the sorting algorithm, for the implementation, it was necessary to define a signal bus returning

0 : !

for a bus of N = 0 signals.

This discussion has taken place before but I don't quite remember the details of it; are there any cases where it wouldn't make sense for the iterators to return

0 : !

for N = 0 iterations?

Ciao,
Dario

Yeah, I've needed this various times as well.

What do you think @orlarey ? Should we do that for par, seq, sum, prodoperators ? https://faustdoc.grame.fr/manual/syntax/#iterations
