In my mind Rust macros are easily the least appreciated feature of the language. Nearly every non-trivial library I've had any contact with use macros in some manner to enhance their API and usually the result is very good. For me one of the most compelling things about Rust when I first learned of the language was print!() and how it comprehensively solves the type-safe string interpolation problem better than anything that has ever been provided in C and C++.
