Two quick thoughts;
Watch out for clashes with square~ (as in x^2) - I thinkk I've seen patches with that trivial abstraction, but it might have been [squared~] Maybe truncate trianglebl~ and varitriangle~ to tribl~ varitri~ (good to keep names less than 8 chars) On Fri, 21 Dec 2007 16:36:03 -0800 Hans-Christoph Steiner <[EMAIL PROTECTED]> wrote: > > I think we can safely eliminate the "osc" from the names since there > won't be a lot of overlap.
