SteveGuo:
Is there a plan to support those kind of types? If support, is it a core language feature or library support?
That will not have a core language support, beside perhaps cent/ucent. At the moment there are no plans for library support, but eventually in some years fixed-size multi-precision integers will be good to have in Phobos, just like several other things, like nD packed arrays (http://pempek.net/articles/2013/08/03/packedarray-random-access-array-tightly-packed-unsigned-integers/ ) etc.
