Namespace imports are a compile time concept only; during runtime
PHP has no general notion of these, only of the fully qualified
names of individual classes, functions, etc.  As such,
implementing this feature would require quite some changes,
possibly having detrimental effects on the engine, and the details
are sufficiently unclear, so this would require the RFC
process[1].

However, I wonder what would be the use-case at all.  How could
that be useful "to aid in autoloading"?
