Remove Custom Array-like Class Configuration

[lessthanjacob]

Changelog

• Removes custom array-like configuration in favor of depending on an interface (Enumerable in this case). Hash is an exception here due to existing implementation details.

Discussion

This was previously discussed as an option, but was decided against due to potentially be too open.
