lint result.unwrap_or_else(|| value)

[bugadani]

Most of the result.unwrap_or_else(|| <some value, or object property>) code can be replaced with result.unwrap_or(<some value>). This is mostly a readability issue and probably gives extra work to the inliner/optimizer similar to other redundant closures.

Thinking about this a little, I think I might be able to implement this lint for at least the subset of cases. Unfortunately it doesn't help that clippy::author doesn't expand closures :)
