It would let you find out if you typed "psuh" instead of "push" in
your chunk of assembly code that you will only be compiling at runtime
in the event it is appropriate for that platform.  Maybe it's not much
better than just doing what the asmjit guys are doing, though.
a.push(ebp);  is already close to looking like assembly, and the
compiler will already check that for typos and proper argument counts
just fine.
