Maybe. It has a lot of practical innovations and constraints but some inconsistencies and rough edges that will likely be addressed. Perhaps programming languages need the freedom to try things, make mistakes and then use feedback with an RFC process, which Rust has, to make improvements. Feel free to submit RFCs if you notice anything specific.

RFCs cannot unwind the complexity on display here in this article, unless the Rust community would entertain a proposal for removing procedural macros entirely, which I assume is a non-starter.

The procedural macro feature of Rust is very simple:you write code that reads a token stream and writes a new token stream. This article might have done something unnecessarily complex, but that doesn't mean the feature is complex.
