More efficient is to change the prototype of ensureSubScopePath:

CStatisticCollection * ensureSubScopePath(const std::initializer_list<const StatsScopeId> & path)

[shamser]

It would. But the suggested change it would no longer be possible to provide an initializer list to ensureSubScopePath. For example, this would no longer be possible ensureSubScopePath({scope1, scope2, scope3}). Do you think we should still go with changing the arg to a reference? @ghalliday
