Agreed, but when comparing between "once-off" try/catch/re-throw blocks vs.
ScopeGuard, I will personally attempt/recommend to use ScopeGuard first and
only fall-back to try/catch/re-throw if that absolutely fails (which is
really not very often). Pure RAII is "best", but typically requires a
slightly higher initial investment.
