Yes, yes, I totally agree! I haven't found the desire to write 
much assembly in many years now as intrinsics are good enough for 
me at this point, but when I did I would rather just write a 
function in C, disassemble it and modify the code. It was more 
pleasant and flexible than dealing with the "clunky way". 
(Besides the built compiler-assembler didn't support the new SIMD 
instructions I wanted to use anyway.)

What I meant was, why do they think that it difficult to 
integrate non-AT&T syntax with the compiler? Makes no sense to me.

Also, assembly is usually defined with the intent to be easy to 
parse. If you don't have to support macros (or other advanced 
features) one can write the core parts of an assembly parser in a 
weekend and having fun while doing it.
