I'm okay with a pseudo type.

My opinion on the matter at this point is such that I care more about
providing an API of sorts to support both kinds of structures, so that any
 developer can write an extension that can leverage this capability and
make this available in user-land.

Having array_some() and array_every() support this doesn't have to be
documented for all I care, if anything it serves as an example of what can
be done.

The most immediate feedback I would like is:
a) whether it's useful to add as an API,
b) a review of the code in `php_traversal.[ch]`
