Re: Const Tuples

[bearophile via Digitalmars-d-learn]

I was just expressing a little frustration :-)

An example; despite it looks simple I am missing something:


import std.typecons: Tuple, tuple;
import std.algorithm: reduce;

struct Foo { int x; }

auto foo(in Tuple!(Foo[]) arg, int) {
    return tuple(arg[0]);
}

void main() {
    int[] data;
    Foo[] empty;
    auto seed = tuple(empty);
    reduce!foo(seed, data);
}


Bye,
