In case someone comes across this old thread
https://dlang.org/phobos/core_int128.html
There was a discussion on this not long ago. Walter tried
implementing it recently too, though I'm guessing he gave up.

There's multiple libraries, one of which i wrote which tries to
address this issue.
One thing you can try doing is using BigInt, and then reducing
to 128bit if/when you need to store the result. Apparently a
number of compilers and back-ends already know how to handle
128bit types (*and maybe larger*), but it's a matter of just
putting it in the D frontend so it generates the appropriate
calls.
