10/10. +9999. . etc. WHY DID THIS TAKE SO LONG ITS BEEN YEARS
It's the single ugliest wart in Swift IMHO. It defies logic. It bites noobs and veterans alike. It leaves tuples crippled and makes everybody's code worse.
I mean, it would be better if you could extend tuples to conform to whatever protocol you need, but good god I just want to use tuples in containers already.
