I think this is basically a good idea, but maybe the API needs a bit of
adjustment --- providing the sizes as an array doesn't seem especially
convenient. Since we only allow up to 6 dimensions (IIRC), what about
six functions with different numbers of parameters:
array_int(int, anyelement)
array_int(int, int, anyelement)
...
array_int(int, int, int, int, int, int, anyelement)
I don't object to having the array-input version too, but seems like in
most cases this way would be easier to use. It wouldn't work well
for providing lower bounds too, but maybe the array-input case is
sufficient for that.
Other thoughts:
* Should the fill value be the first parameter instead of the last?
I'm not sure either way.
* I have a mild preference for "array_fill" instead of "array_init".
* We can handle a null fill value now, but what about nulls in the
dimensions? The alternatives seem to be to return a null array
(not an array of nulls) or throw error.
