Ah, we're having an impedance mismatch.  I'm thinking specifically
about the device tree compiler and some syntactic sugar for using the
label definition to generate /also/ create alias properties. The
hairiness is related to that and the way that dtc is implemented, not
with the final aliases themselves.
