Reply to TSalm,
Yes, you are right.
But this is an example code. The "true" code uses delegates with
argument
which differs from called functions, so I can't point delegate
directly to
them.
And this anonymous function's way is really fastest to code... I must
waiting for a D2 stable version ;-)
Thanks
you can store off the values you need like this:
struct C(R, A...)
{
A args;
R function(A) dg;
static R delegate() opCall(R function(A) dg, A a)
{
C!(R, A) ret;
ret.dg=dg;
foreach(int i,_;A)
ret.args[i] = a[i];
return &ret.fn;
}
R fn() { return dg(args); }
}
// test it
import std.stdio;
int delegate() dg(int i)
{
return C!(int,int)(function int(int j){return j;}, i); // <--- used here
}
void main()
{
auto d = dg(5);
writef("%s\n", d());
}
