This "symbolasm" looks exactly like what Blackfin did.

I think it's a very promising approach - it makes assembly a lot more intuitive, especially to people with background in higher level languages. It makes listings far more immediately readable, even without memorizing every instruction mnemonic. But it just came in too late. By the time Blackfin happened, coding in assembly was firmly an afterthought.

I'd like it to succeed, but I have my doubts that it will.
