So am I. It seems to be incredibly powerful.
Looks to me you can do things like:
1. hook up to COM's IDispatch
2. create 'classes' at runtime
3. add methods to existing classes (monkey patching) that allow such
extensions
4. provide an easy way for users to add plugins to an app
5. the already mentioned "swizzler" functions that are generated at
runtime based on the name of the function
Can you show examples of points 2, 3 and 4?
I can't see antyhing "dynamic" in this feature. I can't invoke an
object's method based on it's name:
class Foo {
void opDispatch(string name)() { ... }
}
Foo foo = new Foo();
string something = get_user_input();
foo.opDispatch!(something)(); // no, can't do it
foo.something(); // not the same...
So where's the magic? I think opDispatch is just another metaprogramming
feature, nothing else.
