I don't really have any ideas as to how to usably only expose passwords
on the C level and not on the Lisp level, since you usually need to do
transforms on the string (base64, etc) before sending it.

I think, perhaps, the most workable scheme for not exposing passwords in
backtraces and the like is the one you've come up with -- the lexical
bindings.

The other scheme that may work is the "have a password data type" think,
which would be oblique to the normal printing routines, but where you'd
have a special accessor to get the real string.  But it seems kinda
heavyweight, especially since the lexical binding thing seems to work
just fine.
