More or less; the particular developer I was thinking of did do a code
review of some of my code where he was exposed to `where` in a `switch
case` statement, but was anware of this construction in a `if|guard
let`.

Yes.

First reaction was some sort of "hmm, that's weird, but okay"; after
pointing out the similar use with `switch` pattern matching and `case
let` bindings he saw the similarity.  I think his overall opinion was
one of just accepting that is "the way it is" in Swift.

I'll try to point him to this thread to see if he has any opinions.
