DXR: no type information for destructured tuple result of enumerate call

[jdm]

The i and e variables declared at http://ncameron.org:8000/rust/source/libserialize/serialize.rs#458 don't have any type information on hover, and the use of i on the next line isn't even flagged as something clickable.

The use on the second line is because it is inside the try! macro - Rust/DXR has no support for macros yet. The declaration of (i, e) should work though, that's a bug.

Since this site doesn't exist any more, can we get some code that would reproduce this?

This should be tracked in https://github.com/nick29581/rust-dxr/ if anywhere.
