Uncertain. I understand the intent behind it, but personally I really like the
where clause as it covers most cases where I need to mix and match, and I feel
that it’s very clean, clear, reads well and encourages best practice. I
definitely prefer the first of these two options:
if let foo = maybeFoo where foo > 5 { … }
if let foo = maybeFoo; foo > 5 { … }
I also get the intent behind semi-colon usage for avoiding ambiguity, but I’d
prefer it to be optional for cases where I really need to use it. We could
perhaps make the compiler more strict to encourage its use though, i.e-
anywhere the comma becomes ambiguous visually a warning could appear suggesting
a semi-colon?

Simplification of some of the features of conditionals would certainly be nice,
and easier to maintain. I wouldn’t say it’s critical though as personally I
don’t encounter many issues with the current syntax.

Hard to say, I like the consistency of having the where clause in regular
conditionals rather than just loops, so I’m not in favour of that change.
Semi-colon use kind of fits with how they’re used for multiple statements on a
line, but I prefer how commas look within conditionals._______________________________________________
