Nonsense. Machine code doesn't have things like commas, brackets and letters, yet we use those in assembly. There's zero reason why you couldn't do my proposal.

Also assembly mnemonics aren't even 1:1 with instructions. Pseudoinstructions do pretty much anything, and even something like `add` can assemble to two different instructions depending on the arguments.

As for writing an assembler being "extremely easy"... yeah no. There's no formal grammar so you're going to be reverse engineering LLVM and GCC's hilariously messy assemblers. Or more realistically, guessing and building an enormous test suite. Not easy at all.
