Re: Support for array_remove and array_replace functions

I'm looking at this patch now.  The restriction of array_remove to
one-dimensional arrays seems a bit annoying.  I see the difficulty:
if the input is multi-dimensional then removing some elements could
lead to a non-rectangular array, which isn't supported.  However,
that could be dealt with by decreeing that the *result* is
one-dimensional and of the necessary length, regardless of the
dimensionality of the input.

I'm not actually certain whether that's a better definition or not.
But one less error case seems like generally a good thing.
