Paul Sokolovsky 59ced651b5 bench: Add test for map() vs inplace operations in array-likes.
map() is 5 times slower. That's mostly because of inefficiency of creating
containers from iterables of unknown length (like map()).

# Array operation
# Type: list, map() call. This method requires allocation of
# the same amount of memory as original array (to hold result
# array). On the other hand, input array stays intact.
