Not really. The rules are there to avoid cyclic initialization 
dependencies, but they are a bit coarse at the moment.

You could put the immutable globals in the the same module as the 
shared ctors, and publicly import them in the "real" modules they 
are intended to be in. You might have to play around with 
`package` protection if you want to make them invisible in the 
helper module, too.
