My view is that Peter wants to keep the code he's adding for the hex,
octal and binary parsing as similar to the existing code as possible.
I very much understand Peter's point of view on that. Consistency is
good. However, if we commit the hex literals patch first, people might
ask "why don't we use bit-wise operators to make the power-of-2 bases
faster?", which seems like a very legitimate question. I asked it,
anyway... On the other hand, if Peter adds the bit-wise operators
then the problem of code inconsistency remains.

As an alternative to those 2 options, I'm proposing we commit this
first then the above dilemma disappears completely.

If this was going to cause huge conflicts with Peter's patch then I
might think differently. I feel like it's a fairly trivial task to
rebase.

If the consensus is that we should fix this afterwards, then I'm happy to delay.
