array_merge is the only one that makes sense. Addition of positional
arrays is nonsensical:
[1,2,3] + [4,5,6] ===> [1,2,3]
As for named keys, every other language with a similar construct
(perl, python, javascript) uses array_merge semantics. Truth is I'm
sorely disappointed that + works like it does, but there's no fixing
it now.
