Virgil Dupras	213614af33	lib/expr: make recursion process a bit more orderly ... Instead of going left and right, finding operators chars and replacing them with nulls, we parse expressions in a more orderly manner, one chunk at a time. I think it qualifies as "recursive descent", but I'm not sure. This allows us to preserve the string we parse and should also make the implementation of parens much easier.	2019-12-29 11:42:18 -05:00
