How can I reflect over package hierarchies in Scala 2.10's reflection? Can I find out what subpackages exist, or what the parent packages are?

Since in general case it's impossible to enumerate packages in a classloader, Scala reflection also doesn't provide this capability. This is unlike the situation with scalac, which is fed a list of directories, which can be enumerated.
Traversing up the hierarchy is easy. Just use symbol.owner.

Are there any changes in Scala 2.12? Are there any possibilities to get sub-packages? – falcon May 04 '18 at 15:33
