I am now proposing the addition of two conventions for handling fuzzy logic:

1) for fuzzy truth statements, a convention that "je'a xi <number>" reflects
the degree of truth of the statement in which it is embedded, thus:

1)	mi je'a xi pinomu blanu
	I am (5%-true) blue.

This is distinct from saying I have a 5% probability of being blue; probability
does not enter into it.  A die has a 1/6 probability of coming up deuce, but
it does so with a degree of truth that is 1 (with 1/6 probability) or 0
(with 5/6 probability): not fuzzy at all.  I had previously proposed this
convention.

Claims using this convention can be rewritten to use "jei" thus:

	da je'a xi <number> broda = le jei da broda du li <number>

2) for scalar claims generally, a new cmavo of selma'o MOI (for discussion
purposes, "fiu'i"), with tentative place structure:

	x1 is at <number> location on scale x2 (of type x3?)

I'm not sure if x3 is useful; it is meant to be filled with things like
"cardinal", "interval", etc.

Comments?
