OK, let's look at these more closely:
> >> array_push(anyarray, anyelement) returns anyarray
The standard spelling for that appears to be somearray || ARRAY[element]
which also has the nice property that it is commutative.
> >> array_pop(anyarray) returns anyelement
That appears to mean that you return somearray[0] and alter the array as a
side effect. How do you plan to do that?
> >> array_subscript(anyarray, int) yields anyelement
That's just somearray[x], no?
> >> singleton_array(anyelement) returns anyarray
That's ARRAY[element].
> >> split(text, text) returns text[]
> >> - split string into array on delimiter
> >> implode(text[], text) returns text
> >> - join array elements into a string using given string delimiter
I can live with these, but perhaps we should choose some not-so-generic
names.
