The sign that is closest to the mathematical "in" sign is the euro sign € but is looks weird [a € b, f(a)] and not every keyboard has this symbol. The @ sign has some idea of containment : [a@b, f(a)] (does it already have a meaning in GP ?). No better solution in mind :-(On Mon, Aug 06, 2012 at 10:23:14AM +0200, Karim Belabas wrote:One remote possibility would be to get rid of 'filtre' (or let it treat comments only) and make spaces significant, as they always should have been :-(. Then we could have the even more natural [ a in b, f(a) ]Unfortunately, both 'in' and '<-' are valid two charater sequences. So using 'in' instead of '<-' would not make any difference, unless you want to forbid variables to be called "in". I do not think it is a sensible idea to allow names to be operators at this stage. We need to keep some unity in the language. Cheers, Bill.
