> No, it's not more difficult to write static analysis tools. I agree it's solvable, but I'd argue it's a bit more difficult to write static analysis tools when macros are implied. But maybe I'm missing something. Here is an example: The subsystem types in the sdl2 crate starting in 0.8.0 are generated by a macro, so racer has issues evaluating the type of video(). A workaround is to explicitly declare the type of renderer. (source: https://github.com/phildawes/racer/issues/337) But my real concern is how to write refactoring tools when macros are implied. It's seems a lot harder than writing static analysis tools, because the refactoring tool wants to examine the source code with macros expanded, but has to modify the source code with macros unexpanded. In other words, the tool has to map from source with expanded macros, back to source

with unexpanded macros. How do you solve that? As a sidenote, I agree that refactoring generated code doesn't sound fun too :-) > How does that describe an unsolved problem? It illustrates that Rust's bifurcation of errors into Result and panics works. I quoted kentonv here because it shows that Rust and Go have converged towards structurally similar solutions to error handling, by using two complementary mechanisms: explicit error checking one one hand (using Result<T,E> in Rust and using multiple return values in Go) and panic/recover on the other hand. The big difference is that Rust have sum types (instead of using multiple return values in Go) and macros (try! instead of repeating `if err != nil { return err }` in Go). > Catching panics is important, yes. No argument there. It doesn't change the overall structure of Rust's error handling story, though. You're right.

I know people complain about the negativity on HN, so this is a minor nitpick. I have been an on-and-off Linux and UNIX user for a while, but ... > It's just a standalone executable that will run anywhere without being installed. See the Releases page for pre-built Linux x64 binaries (you need Rust and GTK+ 3.10 or above installed). Is this not contradictory? Granted, statically linking GTK, 2 or 3, must be ridiculous, but would this still be considered a standalone binary? Granted, I think this might be a variant of libc needs to link to and I am just confused, but I am curious what more knowledgeable people think. Anyway, I am not dismissing this project though. It sounds very cool. I might give it a shot. FYI to everyone, racer is also a core component of making Rust hacking on Emacs wonderful, from what I hear. I have yet to be
