* Merging metadata reduces the number of wrappers required to invoke a function.
* Merging metadata reduces the number of wrappers used to invoke a function.
* This is possible because methods like `_.bind`, `_.curry`, and `_.partial`
* may be applied regardless of execution order. Methods like `_.ary` and `_.rearg`
* augment function arguments, making the order in which they are executed important,
