I just mistakenly tried to naively use self in a macro (which is only invoked by a method taking self), and got the error:

 error: `self` is not available in a static method. Maybe a `self` argument is missing?

As described in #15682, failure is intended due to hygiene. However, the error message is inaccurate, because a macro body is not a static method. It should be changed to take this case into account.

Seems a bit vague without a test case. Closing, but feel free to reopen with more detail.
