To throw my user opinion into this ring (as a long time user of regexes in many different systems) I've always taken the ~ to be short hand for the 'approximately' notation (a squiggly equals) which has good semantic match in my mind: a regex match is sort of a fuzzy equality. With that model, the suggested pair is fairly mnemonic - the 'fuzzy' part i(the pattern) is next to the squiggles, the 'concrete' part goes by the equals. > I have sometimes needed to look up which is which on ~ and ~~. which has no such directionality, so yeah, no hinting there.
