Depends on the expression.
Personally I’d just not have implicit rebinding at all, rather just force rebinding to use := to be explicit but otherwise all matches in all cases otherwise would follow erlangs semantics, no pin operator needed (although I guess you could allow {:ok, :=rebind} = ... to allow in-match rebinding, which would still do the whole invert thing, or maybe :: or something, or ^ since it’s not used anymore with this style).
But yeah, the erlang method feels far more natrual to me, but since I came from erlang that could easily just be bias. ^.^;
I think that piping fixes most of the ‘naming’ issues, otherwise use better names and don’t append numbers.
