I find this use of je'a highly idiomatic and not really consistent with
other usage and the definition.  It really requires redefinition of je'a
to make any sense to anyone who doesn't know the idiom, or "convention".
I do not object in the slightest to this kind of  "slang" outside the
logical and quantificational part of the language. Here I find it like
useing a pipewrench where a tweezers is the appropriate tool.

This is a good example of the problems of semantic overload and multiple
meanings that will occur without provision for language change. All in
all a good argument for the CLD (committee for language design).

djer:

I find the honorable introduction of a new cmavo a perfectly good idea,
but again that makes just John and I so far who think so. Once more,
something for a CLD to chew on.  Fuzzy logic is too important a subject
to be tossed off at the last minute before the Big Freeze.  Decisions
like this lead to confusion later.

But I respect John's effort to accomodate Steven, even though I oppose
it in principle as not a complete and well discussed solution, which it
cannot be given a time lock.
