Interesting. That would indeed address the ambiguity issue.

The notation 'foo means a lifetime called foo.

The non-curly choice is Foo'lt,X,Y. How does that grab you?

Makes sense. One counter point though, which I find more persuasive: the
more common case by far is surely a single lifetime parameter and a single
type parameter. In which case Foo'lt,X seems less noisy than
Foo{'lt}X.
Having said that, Graydon gently invoked BDFL rights to push against using
Personally, Foo'lt, 'xy, X, Y, Z is perfectly readable, and far less
noisy-looking than having two delimited lists one after another. It
will be even more readable with syntax highlighting.
If multiple lifetime parameters were really a common thing I might
have liked a second separator, maybe
(Not sure if anyone cares about my opinion, but: if apostrophes are a
given, the braces of option 8 aren't obviously preferable to me any
more. The appeal of option 8 was that it visually distinguished
lifetime parameters, and just overall looked nice, gave the right
impression. With apostrophes
