On second thought, I think this is fine, since the issue was with enum
bitfields, not bool.

If the bool fields are public, why have the setters? While the following is
elegant:
+ CFG::BuildOptions().setPruneTriviallyFalseEdges(false)
+ .setAddEHEdges(AddEHEdges));
It's probably clearer just to write this as:
CFG::BuildOptions B;
B.PruneTriviallyFalseEdges = false;
B.AddEHEdges = AddEHEdges;_______________________________________________
