This is flawed AFAICS. It assumes that because 1.0 is fixed in specification that there are no bugs in the implementation. To return to my original point, these smart guys are on the record stating that's why they didn't do a self-hosting compiler; good enough for me. :-)

How is this different than having bugs in the C compiler used for the language implementation?

[ralph]

Yes, because of the stableness of the C compiler, bigger test audience, etc., compared to a new language under rapid development.
