This states: "Any unknown member function call to that type is
passed to opDispatch, passing the unknown member function's name
as a string template parameter."
So I tried that. But the compiler didn't like it.
How should I play the game of passing in an unknown member
function name?
```
import std.stdio;
void main()
{
CallLogger!C l;
l.callA(1, 2);
l.callB("ABC");
l.callHome("foo", "bar"); // Fails here
}
struct C
{
void callA(int i, int j)
{
}
void callB(string s)
{
}
}
struct CallLogger(C)
{
C content;
void opDispatch(string name, T...)(T vals)
{
writeln("called ", name);
mixin("content." ~ name)(vals);
}
}
```
Console output:
```
c:\dev\D\D_templates_tutorial\toy1\source\app.d(8): Error: no
property `callHome` for `l` of type `app.CallLogger!(C)`
l.callHome("foo", "bar");
