Could you add a doc string for this?

[iwasaki-kenta]

Might using Stringer for op's be a better option over directly fetching the name of the op?

[twitchyliquid64]

Feel free to integrate stringer for Op if you wish.

Apologies for the confusion, what I meant was to add a doc comment to Get(opcode byte) Op. Its part of the exported API surface, so we need a doc comment so it shows up with documentation in godoc (See the Commentary --> Doc comments section in effective Go for more rationale).
