I haven't looked at the PR, only the RFC, and I did not see this very important detail explained anywhere. The only thing I can see is this rather ambiguous sentence: > The function autoloader will not be called again. That could mean not called again for the current call (compared with proposals that call it a second time with the unequalled name); it could mean not called again for the current line of code (based on the current caching behaviour); or never called again for that combination of namespace and name; or possibly, never called again for that combination of namespace, name, and callback function. That's not a small detail of the implementation, it's a really fundamental difference from previous proposals. So I would like to repeat my first response to your RFC: that it should sound more time explaining your approach to the multiple lookup problem. Regards, Rowan Tommins [IMSoP]
