'Specialize Contains for Iterators in LINQ' PR merged today
"Specialize Contains for Iterators in LINQ" was merged by Stephen Toub into dotnet/runtime main a few hours ago.
Looks likes some crazy % differences, but how common are some of these combinations?
Not all but some seem quite niche and amount to a bit of gatekeeping perhaps and saving devs from themselves, for example, we don't need to OrderBy if we just want Contains right? ...
but still very welcome, am sure they'll benefit many apps in .NET 10 onwards.
