[API Proposal]: Add bool TryGetElementAt<T>(this IEnumerable<T>, out T element)

[alrz]

Background and motivation

This as opposed to checking for bounds each time performing an unguaranteed random access.

Note this could help with any enumerables e.g. arrays, list, so there could be more optimized overloads available.

API Proposal

class Enumerable
{
+  public static bool TryGetElementAt<T>(this IEnumerable<T> source, out T element);
}

API Usage

if (seq.TryGetElementAt(2, out var item)) {

}

Just a note, if your enumerable doesn't have default values, then ElementAtOrDefault could work for your use case.
