## Change the `pipe` function signature
There are many equivalent ways to declare this function, instead of just using the current design.
For example, one could flip its arguments to allow a partially-applied point-free style (see above).
One could also make this a single-argument function so that it only takes the list as argument.
For example, one could flip its arguments so that it becomes function composition on list of functions.
Not only can this function trivially replace pipe; it can also be readily used where a function is expected, such as in `map`.
The current design of `pipe` has the advantage that its asymmetry points at its operating direction, which is quite valuable.
