E.W.Ayers	b6f251bcd3	fix: SubExpr.Pos.toString not terminating ... fixes 1232	2022-06-19 16:04:50 -07:00
E.W.Ayers	18ba16ded9	feat: string representation of Pos ... This is needed because JSON will otherwise lossily convert big nats to floats.	2022-06-17 17:47:51 -07:00
E.W.Ayers	2fe933cdf5	refactor: make SubExpr.Pos a definition ... Instead of an abbreviation. It is easier to understand Pos operations in terms of 'push' and 'pop' rather than through arithmetic.	2022-06-17 17:47:51 -07:00
