Lol I like 'lt
Somehow it makes me laugh compared to the ML usage, but I like it. Perhaps
it plays off my brain's wiring for reading something like "I think &'s are
pretty". (Or for reading "brain's", for that matter.)
I like the {lt} approach ok, too, although not as much. I hadn't noticed
that the ambiguity in your original Option 8 went away when we put the
lifetime in the angle brackets, even if we then used curlies. But yeah, it
feels heavier.

I like this idea too, I just don't like /lt/ for that role.
Maybe `'`? (shades of ML)
&'lt Foo
Foo<'lt>
That actually doesn't look half bad to me.
Maybe `.`?
&.lt Foo
Foo<.lt>
I don't like Foo<.lt>, but &.lt Foo and Foo<lt> might be ok, though it
doesn't adhere to the principle (in that lifetime names are just like any
other identifier).
Another option:
&{lt} Foo
Foo<{lt}>
But the latter form feels pretty sigil heavy.
