Highlight matching angle brackets #23
Description
We have some structs with very long nested types:
type SqrtCli<R, S, T> =
Choose<Eps,
Choose<R,
Choose<S,
Choose<Send<f64, Offer<Recv<f64, Var<Z>>, Var<Z>>>,
T>>>>;It would be very nice to have the syntax highlightingin rust-mode work for angle brackets as well --- as in, highlighting matching delimiters --- since it is a pain to keep track of them yourself. This goes for type parameters in functions, structures, impls and traits as well.
I realize that the problem is to parse < and > differently whether they're used as delimiters or simple less-than/greater-than signs --- a problem that the rustc parser has as well --- but this is something that would help us tremendously. I'm not very familiar with writing indentation modes but if there's any way I can help, please let me know.
It'd probably also be desirable for rust-mode to be able to indent type parameters properly, but the above code isn't the best example of how to do that.
