It would probably be better to combine these `bool` options into a `struct` and then each option has an explicit name that that will be assigned to which makes it explicit which options are being chosen at the call site.

I agree with Shafik, but on the other hand that's the way the API is today. I don't really like the idea of a struct, because that just hides the booleans. Maybe we can use the OptionKind enum directly? Regardless, as you said, that's definitely outside the scope of this patch.

+  void SetInjectCondition(bool inject_condition) {
+    m_inject_condition = inject_condition;
+    m_set_flags.Set(eInjectCondition);
Any reason this should be in the header?
