C++11 – Enumeration Aliasing

[molw5.iwg]

Recently I've been using C++11 enumerations to provide a byte pointer with
stronger strict-aliasing properties. Specifically, I've been using the
definition:

enum byte : uint8_t {};

My reading of the strict-aliasing rules supports the behaviour modern compilers
exhibit in this regard; specifically, byte* aliases only other byte pointers and
raw character points. I'm looking for a second opinion here with respect to the
strict-aliasing rules – additionally, I'd like to know if I'm implicitly relying
on any undefined or implementation-specific behaviour here I may have overlooked.
Thanks in advance,

Actually, it's perfectly legit here. I suspect you will get a
good answer.

It's already up in "Aliasing in C++11" (effectively); re-post.
