EXPLICIT_SCOPE_EXIT

#define EXPLICIT_SCOPE_EXIT    ::ML_NAMESPACE::ScopeGuardDetail::ScopeGuardOnExit() + [&]()

Use this macro in case you like an explicit ScopeGuard.

This is handy if there is a case where you want to dismiss the action to be taken on leaving the scope.

auto localGuard = EXPLICIT_SCOPE_EXIT { foo.needsToBeDoneOnLeavingTheScope(); }; ... if (specialCase) { localGuard.dismiss(); }

Note: Do not forget the semicolon after the closing brace!
