We're trying to keep the number of macros hard-wired into the compiler as small as possible now that we have an infrastructure for dynamically loading syntax extensions at compile time. If this is added, it should be added as a library outside of the compiler. That being said, this use case seems similar to the use case of the fourcc and hexfloat crates, which are really crates that want to be managed by |

Closing due to inactivity, but I think this my belong well in a separate library! |

When testing network serialization routines for a recent project, I found it would be very useful for readability's sake to have a way to write [u8, ..N] byte arrays as hexadecimal strings. This patch introduces the hex_bytes! macro for this purpose.
