Hi,
I would like to know if it's possible to pass the return of a function  
as argument to another function as below:

import std.stdio;

auto foo(int x, int y){
        writeln(x, y);
        return 3, 4;
}

void main(){
        foo(foo(1,2));
}

I would like to print:
1 2
3 4

PS: I tried return a tuple but it doesn't works.

Thanks,

Matheus.

Not directly,  no. But this should work:


import std.stdio;
import std.typecons : tuple;

auto foo(int x, int y){
        writeln(x, y);
        return tuple(3, 4);
}

void main(){
        foo(foo(1,2).tupleof);
}
