TECH: PROPOSED GRAMMAR CHANGE 2$i

CHANGE 42

CURRENT LANGUAGE:

Lojban uses the same words (TAhE/ROI and ZAhO) for space interval modifiers
as for time interval modifiers.  However, they are distinguished with a
"fe'e" flag proceeding any such modifiers.  The rules for multiple
modifiers are that two ZAhOs may be consecutive but two TAhE/ROIs may not.
This rule applies to both time and space.  Once a modifier has been
given, an interval size cannot follow it.  So the following is not grammatical:

	mi ze'a reroi ze'i klama
	I [medium interval] [twice] [short interval] go
	Over a medium period I go twice for a short period each.

PROPOSED CHANGE:

Allow mixtures of ZEhA [PU], TAhE, ROI, and ZAhO for time; and VEhA [PU],
VIhA, FEhE+TAhE, FEhE+ROI, and FEhE+ZAhO for space.  Note that each of
the space interval modifiers must be flagged if there is more than one.

As a side effect, space information may now precede time information
in a tense.

RATIONALE:

Simplicity and uniformity, plus the ability to specify the size of
subintervals.
