Reply to bearophile,
Chris Nicholson-Sauls:My only concern is druntime turning into a "third stdlib." Have to draw a line somewhere.The bigger core becomes, the less stuff (and code) is done in two ways in Tango and Phobos, so I think it's good to have a larger and larger "core". This third stdlib is the common shared one, after all :-) Bye, bearophile
The only things that should go in are the things that both sides can agree on how to do.
