Well... Yes, thanks Yann, but this is clear.
What was not clear to me is that "!" can automagically remove itself from the
arglist.
And even if I think I understand whats going on now, the fact that
process(x,y) = atan2(!,!,!, x, !,!,!, y, !,!,!);
is the valid faust code still amazes me ;)
And. To be honest, I still don't think this logic (syntax) is 100% consistent.
If sin(0:!) or sin(!) is OK, then why is "process = sin()" the syntax error?
Or. Why this doesn't logic work with lambdas ???
Consider
s = +;
process = s(1,!,3);
this works and this is clear (now). But,
s(x,y) = x + y; // same as s = \(x,y).(x + y);
process = s(1,!,3);
leads to "ERROR in sequential composition A:B".
Again, it is not that I think this is wrong, but still.
Oleg.
