Hello all, Various issues have been raised on c.t.t concerning expl3, and I'd like to address them one at a time here (some of the discussion might be quite quick, but I'd like to have a record of which items are "ticked off"). As a starter, lets take two issues I hope can be resolved relatively easily. The "num" data type does not really add to "int", and so l3num seems to be redundant. I've proposed dropping it entirely, and as this has been mentioned again I wonder if there are any good reasons not to. Second, the lack of a "string" data type came up (I'd imagine a string as something \detokenize'd). It seems pretty clear that both strings and floating-point numbers need some support in expl3, so I propose adding place-holder modules "l3str" and "l3fp" with some text in them saying that they will get written at some point. At this stage, I'm not asking for any decisions about what they might do, just suggesting that the modules themselves should exist (which may well push someone to write them). (More items to follow in separate threads: there may be a lot of e-mails from me.) -- Joseph Wright
