This was also suggested on comp.lang.php, recently (the "nested class"
thread), called "namespaces", but there wasn't a lot of enthusiasm for it.
Apparently, it was even implemented at one point, but then subsequently
dropped. I've found it difficult to find the relevant discussion in the
archive (possible the internals-list or Zend's engin2-list), could anyone
provide a link?

I guess package/namespace doesn't have a lot to do with OO (except that they
both allow grouping of functionality, and avoiding name collision, but
that's not the only benefit of OO), but as there hasn't been any enthusiasm
for overloading, either (not even for user-defined types, where you _can_
use "type hints" in function signatures), and it's common in OO languages, I
guess you have a point. Interestingly, I found that Perl has the possibility
of function overloading (also a language that's dynamically typed)
(http://www.math.tu-berlin.de/polymake/perl/overload.html) It also has -
like Python - operator overloading. But is there any enthusiasm for that in
the PHP community, either? Nah...

The common answer is: "Use a prefix"...
