May 18, 2004 Proposal for alias extension | ||||
---|---|---|---|---|

It occurs to me that it would be extremely powerful to be able to do something like: alias SomeClass.* *; and pull in all the methods of that class into the current scope. Uses for this: Proxy classes class Proxy(T) { ... alias T.* *; } More powerful mixins: template Foo(T) { alias T.* *; } class Mixed { SomeClass X; mixin Foo!(X); this() { X = new SomeClass; } } Of course, it would be even simpler and more powerful if mixins had constructors... But that rant is already somewhere ;) I know this approaches the "accidental inclusion of a compile-time functional language", but this would be incredibly powerful. One thought that comes to mind: this probably should not pull in operator overloads and such, only regular methods. Thoughts? Mike Swieton __ It's kind of fun to do the impossible. - Walt Disney |

Posted in reply to Mike Swieton | isn't that what mixins are made for now?
