eitherRef

This overload enables, when possible, lvalue return.

BUG: this overload is not chosen over std.algorithm.either so function must currently be called eitherRef instead of either.

ref

Ts[0]

eitherRef

(

Ts...

)

(

ref Ts a

)

if (

a.length != 0 &&

allSame!Ts

)

Examples

int x = 1, y = 2;
eitherRef(x, y) = 3;
assert(x == 3);
assert(y == 2);
