It's not an issue introduced in this pr. I wonder if this could be refactored? If so, I can work on it. But just in case you have easy answer already, so I don't have to do further investigation.

I agree, I would prefer having classes for the instruction where all the instruction functionality would be.
As it's now the opcodes are reapted everywhere, instead it should just be in in-place, this class.
And then have classes for instruction sequence where we keep all functionality gathered.
