This implements RFC 3697, "Declarative (
macro_rules!) attribute macros".I would suggest reading this commit-by-commit. This first introduces the
feature gate, then adds parsing for attribute rules (doing nothing with them),
then adds the ability to look up and apply
macro_rules!attributes by path,then adds support for local attributes, then adds a test, and finally makes
various improvements to errors.
