r? @joshtriplett for T-libs member review I am not sure this pulls enough weight over the insert_with method, but it's also pretty common to have _default variants in std, so not really opposed. |

This seems reasonable to me. The naming seems consistent with other methods in std. However, this should not be added as insta-stable. This needs to be marked unstable (the feature-gate name seems fine), and it needs a tracking issue. r=me if made unstable with a tracking issue. |

…=joshtriplett Add Option::get_or_default Tracking issue: rust-lang#82901 The original issue is rust-lang#55042, which was closed, but for an invalid reason (see discussion there). Opening this to reconsider (I hope that's okay). It seems like the only gap for `Option` being "entry-like". I ran into a need for this method where I had a `Vec<Option<MyData>>` and wanted to do `vec[n].get_or_default().my_data_method()`. Using an `Option` as an inner component of a data structure is probably where the need for this will normally arise.
