Wonderful talk, Iain. :-)
One question about the copyright assignment issue. How does this operate in practice? Is it going to be that the D frontend will simply go forward as copyright (c) FSF (which isn't a problem DMD-wise as their assignment agreement immediately licenses the code back under completely unrestricted terms), or will it operate on a per-release basis (where basically every time a new D frontend release is pushed to GCC, the copyright is also transferred)?
