I think the code you linked shows exactly why generics are needed for these kinds of methods. By introducing a single generic, you could reduce it from 500 lines to 20, and make it work for all types, not just the built-in ones. It would also remove the need to have different method names.

I think that makes it less complex, as the developer doesn't need to think about the exact underlying type of the array when calling Take (which is irrelevant to its implementation).
