Arf, I'm sorry but looking at the implementation, this is a false promise. This doesn't show aliases but only the class of the source service. This works for services that use the id=fqcn convention, but that's inaccurate in the general case.

ContainerBuilderDebugDumpPass runsBEFORE_REMOVING which meansResolveReferencesToAliasesPass already ran and we lost the information that would be needed to achieve this.

I don't know if we can reorder the passes to dump before resolving, but as is, this PR doesn't make sense to me.

If we dump before resolving, we might end up missing other information in the debug commands by displaying the state before most compiler pass have run

@nicolas-grekas oki i got you, to be fair I've juste restarted it, blindly copy/pasting for now so the PR get visible
if, for actual code in container, its not possible lets close as wontfix
thx
