The is8Bit check here is unneeded extra code.

Not sure why you chose pair over tuple here for return value.

There is no need for a tuple; pairs require exactly two inner types and tuples allow for an arbitrary number. However, I only need two. AFAIK, that's the only relevant difference between pair and tuple.
