Ok.  If you're not planning on extending the front-end,  
understandability doesn't really matter ;-).  I get where you're

Ok.  For most users to be interested in it, it would have to be faster  
or produce better code, and be as correct as G++.  I'll be interested  
to see how it comes out.

Ah, nifty.  I no nothing of that processor, but you can build a  
backend independent of the front-end :)
