func something and somethings.go

func (it *instructionTranslator) transferInstructionSets(sets []*bytecode.InstructionSet) []*instructionSet {
	iss := []*instructionSet{}

	for _, set := range sets {
		it.transferInstructionSet(iss, set)
	}

	return iss
}

func (it *instructionTranslator) transferInstructionSet(iss []*instructionSet, set *bytecode.InstructionSet) {
	is := &instructionSet{filename: it.filename}
	it.setMetadata(is, set)

	for _, i := range set.Instructions {
		it.transferInstruction(is, i)
	}

	is.paramTypes = set.ArgTypes()

	iss = append(iss, is)
}

this kind of structure is not awkward
