Is [10, _..] the same as matching [10, ..]? I would find it clearer that way if the behavior is the same.

I wrote [10, ..] first. But the latest release of rustfmt changed it into [10, _..] so I assumed the latter was the preferred way of writing it 🤷♂️

Seems like a bug in rustfmt. I filed rust-lang/rustfmt#2909 to follow up. I would recommend using .. in this PR.

…nt, r=TimNN Idiomatic improvements to IP method Since match ergonomics and slice patterns are stable this might be more idiomatic modern Rust implementations of these methods? Or well, slice patterns with `..` are not stabilized yet, so maybe we want to specify all fields but with `_`?
