I agree a "strict" parsing, considering all attributes relevant, that disallows `box radius 3' would ease writing pictures with less puzzling over how something's been parsed. > The fact that 2d gets tokenized differently from 2nd is also > disconcerting. Dropping irrelevancies doesn't help `move 2d' being `move 2 d' because nothing is irrelevant. So the lexer would go for the longest match, making `2d' the token, but then complain when it isn't a NUMBER, because of the unused `d', nor an ORDINAL? -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
