Well one thing that seems clear from this example -- we now have
__traits(isSame) to tell if lambdas are the same, but it looks like the
compiler doesn't subscribe to that belief...

We should fix that...
Yeah. That part of lambdas has always been a problem. My guess here is that
the problem stems from the fact that they're declared in separate scopes,
but I don't know. Regardless of the reason for the failure though, that
example really needs to work, or most anything that cares about lambdas
being the same is going to have problems.
I think that's exactly the problem: I assumed that it's about the
lambdas and associated types but would have never guessed that names,
scope etc. play a role as well. Is this somewhere documented? Or at
least a hint, would help a lot to be aware of this pitfall.
