I'm looking forward to see it.

In principle, I don't see a problem if the "dir()" builtin on a java
package initialized the java classes, but your argumentation for doing
so is weak. The cache code must be robust in all cases. If it isn't, its
a bug that must be fixed.

Implementationwise, both "from xx import *" and "dir()" uses the
__dir__() hook, so do you propose make them diffrent?
