I haven't looked at the PR, only the RFC, and I did not see this very impo=
rtant detail explained anywhere=2E The only thing I can see is this rather =
ambiguous sentence:

>  The function autoloader will not be called again=2E=20

That could mean not called again for the current call (compared with propo=
sals that call it a second time with the unequalled name); it could mean no=
t called again for the current line of code (based on the current caching b=
ehaviour); 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=2E

That's not a small detail of the implementation, it's a really fundamental=
 difference from previous proposals=2E=20

So I would like to repeat my first response to your RFC: that it should so=
und more time explaining your approach to the multiple lookup problem=2E
