I don't think this is sufficient.  Imagine a group of modules that really 
_do_ have a cyclic dependency, and a mixin that adds an independent static 
this.  Ideally you'd be able to mark the mixed-in constructor as independent 
without tainting the whole module.

So just make the pragma apply to declarations, you either mark specific 
functions (which can then be mixed in) or put `pragma(...):` at the top of 
your module and you get your behaviour.
