TECH: PROPOSED GRAMMAR CHANGE 2$i

CHANGE 46

CURRENT LANGUAGE:

Termsets are a pair of term sequences joined by a logical connective;
the start is NUhI and the elidable terminator is NUhU.  The logical
connective can be afterthought EK, in which case NUhU must precede it,
or forethought GEK-GIK, in which case NUhU must precede the GIK.

PROPOSED CHANGE:

The syntax "NUhI terms NUhU EK terms /NUhU/" is REMOVED from Lojban.
It is a hybrid of forethought (the NUhI) and afterthought, and is
overly restrictive.

Instead, a "term group" construct is introduced, joining the terms
with the new cmavo "ce'e" of the new selma'o CEhE.  A logical connective
is permitted but not required, thus:  "term ce'e term ... pe'e EK term
ce'e term ..."  "pe'e" belongs to the new selma'o PEhE.

The corresponding forethought syntax remains "NUhI GEK terms NUhU GIK
terms NUhU", and the syntax "NUhI terms NUhU", with no logical connective,
is added as well.

RATIONALE:

1) Afterthought termset logical connection becomes genuinely afterthought,
without the need for any special start cmavo.

2) Providing termsets without logical connectives (in both forethought
and afterthought forms) provides cmavo grouping to solve two unrelated
problems.  By grouping a "se BAI" with a "te BAI" (or "ve BAI, or whatever)
we can require that both BAIs refer to the same underlying event:

	se ka'a ko'a ce'e te ka'a ko'e

The presence of the "ce'e" makes sure that "ko'a" is the destination and
"ko'e" the destination of the same act of going.

The other problem is that of indicating that two numerically quantified
sumti have co-equal scope:

	ci nanmu re gerku cu batci

says that three men bite two dogs each, for a possible total of six dogs,
whereas

	ci nanmu ce'e re gerku cu batci
	nu'i ci nanmu re gerku nu'u cu batci

says that three men bite two dogs each, the same two dogs.
