----------------------------------------
That looks ok.. how did you test, where do the savings come from, and how much savings?

> Right now, there is TUPLE, SMALLTUPLE, and TINYTUPLE to try and save space when writing out Tuples. There is no reason, however, that this can't be hardcoded for common tuple sizes (<10) to further save space. A quick fix that has positive benefits.
