AFAIK, it's always a miss. There's a bug report somewhere where
Kenji explained exactly why it works the way that it does, but
I don't recall what he said. I also don't know if it was closed
as "won't fix" or remember much that would make it easy to
find, unfortunately. :|
But there is a technical reason for the limitation, even if I
don't remember what it is.
It's to prevent UFCS functions from being shadowed by local
variables. From the spec:
Rationale: Local function symbols are not considered by UFCS to
avoid unexpected name conflicts.
