Nicolas I do not criticise the implementation, Iâm too stupid for that. For us this is the conceptual overload our problem. There should be one number parser in the core. Now I would love to have nicely packaged extensions that are call ExternalParsers with nice tests and documentation (Iâm even willing to spend time writing it if there are some tests). And this package would be a really important one. You see related to that when I was young and bold I thought that we must enhance the time and date in the core. And we did it back then in Squeak. Now if I would have to redo it I would do it that way: keep a nice and minimal (not too minimal) core in the language AND have really nicely packaged frameworks supporting calendars, time zones and others. so that the programmers can choose.
