    It seems i've been peddling misinformation - the ref-counting smart_ptr equivalent has been removed from the Rust language.



    Screw it, i'll bite.

    The Rust FFI no longer uses stack-switching when calling external C functions. As far as the C interface itself, it is still under development like the...

    But by virtue of being interpreted or just very high-level they cannot compete with C in the areas that have made C as popular as it is. Rust is one of a number of new languages (see Nimrod for...

    It is absolutely unique to C++ in the sense that no other language contains its own predecessor as a subset (at least none that i know of?). I did not say everyone who writes C code and passes it off...

    I just don't see how this in any way works as an argument against stronger type safety always being an advantage? If you want to do type unsafe things, then the only way you're gonna be able to do it...

    I'd challenge the statement that this is commonly done in games, this seems like a horrible design to me. Nonetheless, if someone really wants to do this they can, by jumping through hoops,...

    Rust has pattern matching and recursion. It also has regular conditionals and for/while loops. Nobody is forced to stick to immutable variables either, it is just the default type of variable.

    I'm not familiar with Erlang, but a quick Google tells me Erlang uses single-assignment; so that would be a tentative yes.

    No, no it doesn't. The narrow views that you claim i have of C++ seems to be matched to an equal extent by the narrow views you have of Rust. The only thing that _needs_ to be mutable is the state of...

    In that sense Rust is closer to C++ than it is to C and is already quite large. I think the claim that it can or will replace C stems from the fact that it has the potential to match C in terms of...
