[swift-evolution] [Pitch] Retiring `where` from for-in loops

[Vladimir.S]

FWIW I don't think we need all "4", just like we don't need `unless` as a 
pair to current `if` or `until` as a pair for current `while` loop.

I.e. we have "continue" with current `where`, and you can use boolean 
inversion `!`. As for "break"(while) - my opinion the for-in loop will be 
more powerful and adds fun for coding (from wwdc keynote - "Swift is a 
powerful language.. writing Swift code is *fun*..." my opinion: using 
guard-continue or guard-break is *not* fun ).

So in your words, it is better add *one* then remove *one*.

The only question I'm not sure about if we should keep 'where' and 'while' 
keywords for these features, or rename them. For me it's OK to have 'where' 
and 'while' but probably I'll support another more clear keywords.
