WRT functions: while I could see how this would seem like a good idea
because of the symmetry in what's going on at a very high level of
abstraction, I would be against including it in a language. I don't
particularly like it for arrays, but it does make it easy to add items
into an array, which happens pretty often in development, especially
when writing exploratory code. Function signatures, on the other hand,
probably aren't changing nearly as often.
At the very least, I wouldn't want to encourage people to make
functions with many parameters, as it's normally a sign of poor
design. This wouldn't explicitly do so, but would do so implicitly as
it's only real purpose is to make it easier to add things.
As far as the supporting-a-leading-comma thing goes, I'm pretty
ambivalent on it. I don't really like the style outside of Haskell
code, but that's just a preference.
