After tweaking dmd a bit litte, i get the dotexp overloading work.
The following is the test code:
import std.stdio;
class c
{
B opDotExp(char[] methodname,...)
{
writefln("god it works ", methodname);
return new B();
}
void opAdd(int j)
{
}
void test()
{
}
}
class a:c
{
}
class B
{
int i;
B opAssign(int k){
i=k;
return this;
}
}
char[] v1;
void func(char[] v, ...){}
void main()
{
a v=new a;
v.test();
v.dynamicmethod(3,4);
//v.qq = 5;
writefln((v.qq = 5).i);
}
it generates the output:
god it works dynamicmethod
god it works qq
5
Any comments? Do you like this feature?
Cool! I suggest the rewrite:
c.unknownmethod(args) -> c.opDotExp!("unknownmethod")(args)
That way you have the option of handling the method name statically or
dynamically.

Yes, this also helps to catch errors at compile-time (like, dynObject.lenght vs
dynObject.length).
