I don't think this would be a problem in practice since it is hard for me
to imagine an API that would use 'inout' as a label -- at least they would
spell it 'inOut' according to our API guidelines (but I really think they
should call it something else).

There's also a possibility that we add 'out' parameters in the future, and
if 'inout' would be spelled '&', then we would need to find another sigil
for 'out'.

So, overall, I don't support this.
