Although I am not a huge fan of method chaining in general (see [1]),
I am happy to have it in PHP as it faciliates fluent interfaces [2].
I makes IMHO perfect sense to also allow a similar syntax for arrays.
But the implementation should be closed (in the mathematical sense), so
that $o->m()[0]->n() also works, for instance, when m() returns an
array that has an object with method n() at index 0.
