Cool! Only this does not show me where the error was. __FILE__
and __LINE__ is not any help here, because it's a template. Any
other way to find out where the actual error was?
Nah, this gives me lots of compiler crap, like .empty and others,
when compiler tries to compile them.

You can test the mixin with static if, like this:

I don't know. I never used private in conjunction with a template.
Le
Thanks a lot!
There is a problem though: when i pass incorrect parameters to
such a method, it says, that S has no such field, which is a
misleading error message.
There is also a problem: when i declare opDispatch to be private,
i still have access to this forwarding from another package. Is
it a bug or what?
You can use 'auto' to let the compiler deduce the return type. Here I
use 'foo' which returns an int and 'bar', which returns void.
struct SomeT {
int foo(double d) { return 0;}
void bar(double d) { return;}
}
struct S {
auto /* here */
opDispatch(string name, Args...)(Args arg

Oh, my bad, "alias impl this;" actually did work. But the first
argument problem still holds.

I tried this:
struct S {
R opDispatch(string name, R, Args...)(Args args) {
return mixin("(*iface)." ~ name)(iface, args);
}
SomeT ** iface;
}
But then val.foo(1, 2) gives me "no property 'foo' for type 'S'".
I've seen the template solution:
struct S {
10 matches
