saugns v0.3.6. Redesign. Fix for undocumented feature. Make parser handling of operator sublists simpler and more generic, moving specifics to parseconv. Refactor scriptconv and program.h types. Make use of '[]' separately from list parameters function as a generic subscope with few effects. This feature is still undocumented. Mostly harmless. (Originally, as '<>', it simply allowed freer use of whitespace. This was broken by the time of the 2012 releases.)
