Eh, as long as a feature wasn’t removed for security or correctness reasons
(which isn’t the case with SE-0007), I don’t see a problem with one proposal
enabling functionality that was removed by another. It’s not like we said
C-style for loops are evil or anything, just that they weren’t right for Swift.
If it turns out that something which otherwise is right for Swift can be
“abused” to get C-style for loop semantics, then those who voted against
SE-0007 are free to try out this new syntax and see if that helps them. IMHO,
anyway.
