At a pure LaTeX3 level, I think we may move in that direction to some extent (although I think \item[...] is a good example where there is simple alternative). Frank has pointed out that at this stage we want to keep the user syntax for LaTeX3 'open', but I always point out that 'something like LaTeX2e but more organised' is a likelihood. To me, that means   \foo[...]{...} is a possible, but I'd hope not   \foo{...}[...] (i.e. I'm in favour a a single optional argument, which should come first, at least as a standard approach.) -- Joseph Wright
