Could module-level globals be treated like local variables to the static constructor for the purpose of checking purity?

AKA
static this() pure
{
  // trivial stuff
  // calls weakly pure functions
  // writes module-level globals
  // reads module-level globals
  // etc...
}


That's compiler enforceable and effectively means that stati constructor does not count as part of a cyclic dependency...
