in the future these can and will change (new operands, new instructions) and i would prefer they not be major breaking changes. applications can ignore them and probably do undesired variants anyway.

if you want to write a 1120-variant match, are you me? why would you do this

in real programs, having read_operands inlined hurts performance!

the in-repo benchmark got better with this inlined but it's probably
better to leave it up to the compiler when finally stitching stuff
together. i suspect that having read_operands inlined resulted in just
too many live values, and the compiler was inspired to play hijinks that
pipelined poorly. disas-bench shows a ~15% improvement from this change.
