Tested against

letthreePart=(("yup",1s),2,3,4,5,6,7,8,9,10,11, Some 12,13,"nope",17,18, ValueSome 19)letonePart=("yup",1s)

There's one little problem though. When values of the wrong type are passed to the precomputed constructor, InvalidCastException is now thrown instead of ArgumentException (MakeTuple still throws this as well). I'm not sure if this matters that much (I suspect a similar change sneaked into #9784), but if it does, I could theoretically emit a runtime check throwing the old exception here at the cost of a small performance hit.

This is technically a breaking change given the change in exception that's thrown, but I think that's a very minor thing given the perf benefits.

Could you update the failing test?
