What performance penalty?

Lua pushes all the arguments to the stack to invoke S(1,2,3),
and inside S() Lua pushes them AGAIN for constructing a table.
"VARARG" bytecode is not O(1) instruction, it was discussed earlier in this
list.

There's no VARARG bytecode involved in this case, it's just a plain function call.

Please show your implementation of array constructor S() which does not have VARARG bytecode inside.
