local function f(...)
    print(#{...})

f("A","B","C")

works fine and prints 3 (at the cost of creating a temporary table)

    1    [4]    GETGLOBAL    1 -1    ; print
    2    [4]    NEWTABLE     2 0 0
    3    [4]    VARARG       3 0
    4    [4]    SETLIST      2 0 1    ; 1
    5    [4]    LEN          2 2
    6    [4]    CALL         1 2 1
    7    [5]    RETURN       0 1
