I agree, even though covering all cases in a consistent syntax does not seem hard:

Tuple[int] - variable length homogeneous tuple.
Tuple[int,float] - length 2
Tuple[int,] - length 1
Tuple[()] - length 0

Since length 1 and more so length 0 cases don't seem to get much use, a somewhat non-obvious syntax should be fine.
