>I fundamentally do not believe pulling arbitrary files into such a struct=

=20

I don't think anybody, in any of the examples on this thread, has ever sug=
gested listing individual files to be loaded into the container/module/what=
ever=2E=20

The suggestions I can think of have been:=20

- track things recursively, e=2Eg=2E if A=2Ephp is in the container, and l=
oads B=2Ephp, put B=2Ephp in the container

- choose based on directory, e=2Eg=2E whenever the file path being loaded =
begins "/var/www/plugins/foo", put it in the container (this seems by far t=
he simplest to me)

- choose based on being in a Phar archive, i=2Ee=2E whenever the file path=
 being loaded begins "phar:/var/www/plugins/foo=2Ephar:" (this seems entire=
ly equivalent to the previous point to me)=20

Perhaps what you're picturing is that the compiler needs to know up front =
what classes do and don't exist, so want to create some kind of index? That=
's not how I picture it=2E If code in the container references a class that=
 doesn't exist, it should call any autoloaders registered *inside* the cont=
ainer, and if they fail to define the class, it should error as normal=2E

There needs to be some way to "import" and "export" symbols to communicate=
 between the container and its host application, but I think for *those* it=
 is safe to list individual items, because you're not trying to pull their =
dependencies, just point to the right piece of code=2E
