Tuple is a mathematical term predating computers, and the "-tuple" suffix is older again, so pronunciation shouldn't be as ambiguous as the other, newly invented terms.

(It's historically rhymed with couple)

On the other hand, a lot of Latin-originating words have had their pronunciations changed in US English, the canonical example being data (from UK English "da-ta" to US English "day-ta", which has now begun to become standard everywhere due to the tech industry) so I guess other words could go the same way.

So it's true! It is pronounced with a short initial syllable. I've always pronounced it along the lines of toople.

Surely day-ta and da-ta are the wrong way round there?

Unless I've worded it confusingly, I don't think so...

I'd always heard "Two Pull"s as the one true way, not to be confused with "Triple"s.

"Tup Lee" just seems silly.

Not to pick on the place that invented "Sweet Tea" and BBQ, but in the south, ya'll just need to drag out those vowels....

Or my favorite, combining your first two choices: too-pull.
