Wouldn't the sigil be .identifier instead of 'identifier? Anyhow, I
have some thoughts on this, but no time to reply atm.

I would also find it valuable to have a particular sigil for
lifetimes, as there is for the various pointers.

I expect it would, but at the expense of no longer being able to
make as simple a statement in the language tutorial as this:
The notation 'foo means a lifetime called "foo".
To me, it seems nicer for a newbie to wonder "how is that lifetime
being used?" than to wonder "what's that thing after the dot?"

Would using a dot '.' instead of a quote ' also resolve the

+1 to this. Option 8 was always the best-case syntax, and
prefixing an apostrophe on lifetime names is entirely inoffensive.

Interesting. That would indeed address the ambiguity issue.

This does need a lookahead but as far as I can tell
unambiguous and manageable. More on:
