I keep coming back recently to the idea of native support for "packages" 
or "modules":

- a bunch of classes edited as separate files, but loaded "in one hit", 
rather than autoloaded one class at a time
- a more "solid" namespace, e.g. visible in Reflection
- configuration of declare()-style directives that apply to the whole module
- "module private" visibility for classes (and maybe, later, methods, 
although the phrase "private protected" [1] makes my head hurt)

I think this would fit naturally with preloading, and making OpCache 
(and JIT) more central to the engine, and fits more naturally with where 
things like Composer and PHP-FIG have taken the language.

It might even link to FFI - maybe a module linking to C functions in a 
certain way could act as a light-weight, dynamically-loadable, extension.

I realise I'm dreaming now, and don't expect this to all suddenly appear 
in 8.0, but I wonder if it's worth exploring as a framework to build 
around / toward?
