I agree.

I don't agree. In this moment of the D development it's still more important to design D well than to squeeze every bit of performance out of the reference implementation.

Example: currently vector operations have some small syntax (and maybe semantic) problem, plus performance problems. I think fixing their syntax is currently more important.

Fixing performance problems is possible to do later in GDC/LDC if the language design is good, but fixing the syntax later is quite harder to do.
