"Implicit initialization" (CRType oImp = oCopied;) and "explicit initialization" (CRType oExp(oCopied);) are equivalent in the sense that they both invoke CRType's "copy-constructor". The copy-constructor's signature is CRType::CRType(const CRType& aroCopied). This same copy-constructor will also be called whenever an object is passed-by-value into some function.
