The presence of an extra comma would leave me second-guessing the
behavior on multiple returns too. In any case, it should do the same
as the table constructor. Went to check what the table constructor
does:
Lua 5.1.2 Copyright (C) 1994-2007 Lua.org, PUC-Rio
function f() return 1, 2 end
t = { f() }
print(t[1], t[2])
1 2
u = { f(), }
print(u[1], u[2])
1 2
v = { f(), 3 }
print(v[1], v[2])
1 3
So, yes, if function calls were to accept a trailing comma, I think
they should just drop the comma and not impose special behavior on
multiple returns, for consistency with the table constructor.
