No, it's meant to turn "return (h(table,index))" into "return h(table,index)"It was thus said that the Great Thiago L. once stated:I just realised this could be another case for my old suggestion [1] about '...' as a suffix operator which means, explicitly, "do not truncate this list of values". My original suggestion was for function call arguments, so: func(a()..., b, c) ...would not truncate the return values of a(), as it normally would. But another case could be for this case, so: local a, b, c = t[1]...t = { 'one' , 'two' , 'three' } local a, b, c = t[1]... a == 'one', that's fine. What does b and c equal?Whatever ({mt.__index(1)})[2] and ({mt.__index(1)})[3] would be...Well, two things: 1) the syntax is t[1]... (note trailing dots) which is meant to indicate multiple values starting at the given index (from what I understand the proposal to mean).
2) there is no metatable.
Another question:
t = { one = 1 , two = 2 , three = 3 }
local a,b,c in t['one']...
What does b and c equal?
