Subject: Re: Sprouts notation

I propose using parentheses in this neo-Glop notation in a different
way:  Parentheses can enclose a pivot/loop chain as proposed by Josh
Purinton in another sprouts-theory thread.  If we add my other proposal,
that parentheses be used in pivot/loop notation to enclose neo-Glop
notation, we can use double sets of parentheses if neo-Glop needs
grouping.  I'm not sure about a good notation for repetition in
neo-Glop, but pivot/loop notation makes most of it unnecessary.

When parentheses are used in pivot/loop notation, I expect they
introduce a new boundary in the region.  In neo-Glop, parentheses
may introduce part of a boundary, as in 0.2(L1)<(P2)> , which means
0.2AB<C>/0.AB/0.0.C .
