Is it possible to override std tuple's toString format?
so that
auto a = tuple("hello",1,2,3);
writeln(a);
prints
("hello", 1, 2, 3)
and not
Tuple!(string, int, int, int)("hello", 1, 2, 3)
I'm aware I could write a custom formatter function, but it would
be nic
Thanks! that was perfect.

The title

allows them"
of
https://github.com/D-Programming-Language/phobos/pull/2227/files
made me curious to what is meant by ref return. Is this a recent
improvement in DMD?
Ali Çehreli:
Here is a workaround:
unittest {
size_t delegate()[size_t] events;
auto makeClosure(size_t i) {
return { return i; };
}
foreach( i; 1..4 ) {
events[i] = makeClosure(i);
}
You can also use two lambdas to do that, without the

Hah, sorry, I didn't read the last post. I did exactly what Ali
just suggested.
I've run across this myself. The workaround I used was to call a
function from inside the foreach loop, and in that function you
construct the delegate (with the index variable passed as a
parameter).
