I can not come up with a compelling arguement right now,
much like I could not come up with one, say, 20 years ago.

Except that, it seems customary to have a data type double
the available CPU/OS max bit size.

Ah, here is one: what happens if I wanted to multiply
2 Int64 numbers?

I don't know why I would need to do it right now, though :-)
