Please comment: http://wiki.dlang.org/DIP25
How will that interact with designs like the singleton used in e.g.
std.random.rndGen:
@property ref Random rndGen() @safe
{
import std.algorithm : map, repeat;
static Random result;
static bool initialized;
if (!initialized)
{
static if(isSeedable!(Random, typeof(map!((a) =>
unpredictableSeed)(repeat(0)))))
result.seed(map!((a) => unpredictableSeed)(repeat(0)));
else
result = Random(unpredictableSeed);
initialized = true;
}
return result;
}
... will it be as simple as adding an 'inout' qualifier to the method and/or
return type? In any case I think it's a use-case worth adding to the example list.
