Hello everybody, If this mixin example works: > template Foo(T) > { > T x = 5; > } Why this one not: > template Foo(T) > { > T x; > x = 5; // <- error: no identifier for declarator x > } On page describing mixins I never saw an example with assignment inside mixin body, is it limitation of language or bug? Thanks. -- serg. |

The problem here is that a template() declaration is a scope that contains other declarations - it is not a scope that contains code. This is why it complains about their being 'no identifier for declarator', as it was expecting a type before the 'x'. -- - EricAnderton at yahoo |
