I would do that:

Implementation:

rootsInsidePackage := [ :packageName |

| myPackage |

myPackage := RPackageOrganizer default packageNamed: packageName.

myPackage definedClasses select: [ :each | each superclass package ~~ myPackage ] ].

Example use-case:

rootsInsidePackage value: 'OpalCompiler-Core'

Is that what you expected ?

Hi

Given a package I would like to know the classes that are roots
of hierarchy inside the package.

Do we have something like that?
