Hi!
While Enumerable does not provide `#compact` method, it requires changing code in some cases to substitute array with enumerator.
For example, to reduce memory usage it's usual to change `large_array.map { to_heavy_object }.chained_methods` to `large_array.lazy...`. However if `chained_methods` contains `compact`, this change will fail. Replacing `compact` with `reject(&:nil?)` fixes it.
What do you think about adding `#compact` to Enumerable?
