OK.  Now that I have refreshed my memory, i see this.

But then "zi" as tcita should correspond to "vi" as a tcita to be
consistent, and changing the meaning of "vi" as a tcita is pretty major,
even though:

Actually, having checked, "vi" is normally an ellipsis for "bu'uvi", and
"zi" an ellipsis for either "bazi" or "puzi".  The thing is that you
MUST be able to interpret these things as elliptical versions of more
complete tenses, not that they have to be consistent.  Both have real
current usages as tenses on the bridi, and the usage as sumti tcita
right now is consistent with the bridi tense.  Your proposal separates
the tense usage from the tcita usage, and indeed I am not sure I see any
ellipsis that makes a lot of sense for zi marking the sumti as you

The only other case where tcita usage differs from tense/modal usage is
for the perfectives which you often complain are backwards.  But even
backwards is still a clear relationship between the tcita ZAhO and the
tense ZAhO.  "zi" as a tense doesn't seem to make a lot of sense in
terms of an ellipsized sumti, using your scheme.

and I would just use "ba'o lei mu mintu" or more likely "ba'o le mintu

OK, I got confused here.  But if "zi" was to be used as you suggest then
by correspondence "vi" as a tcita would have to label a distance.

Re the dakau/ke'a issue - OK you have convinced me that the two usages
of kau would conflict.  I do not feel ke'a is the way to go, subscript
or no.  I would rather use a new cmavo.  In any case, this one needs to
go on the issues list to be resolved.  Or rather both of them, since I
think we had been thinking both could be handled by kau under the lambda
concept. dakau should mean one or the other, and we need a universally
unambiguous way to do the other.  I don't think ke'a is good enough.

I don't understand lambda calculus in the least, but if the need in
lambda calculus is for more than one variable, THAT sounds like a good
use for a KOhA with subscripts.  Only rarely would anyone need multiple
variables.  So which of the two problems fits more closely with lambda
notation, or if both do, how could we resolve them with subscripted
variables instead of kau.

(Note for new Lojbanists/subscribers - the fact that this discussion is
grossly abstruse should not be considered threatening.  These are minor
issues and when resolved can be explained to those who aren't logic
fanatics with relatively simple usage guidelines.  Indeed, our
discussions thesse days seem to all be overly technical, which may mean
that only issues that will have no significant effect on normal usage
are really left to decide.)
