Statically typed Python utilities for functional programming.
This class is useful for programming in the collection pipeline style. It wraps a homogenous variadic tuple and exposes a fluent interface with common functional programming operations. Why a tuple and not a "lazy" iterator? Because a tuple is relatively immutable and because, in my opinion, reified collections are much easier to reason about than stateful iterators (at the expense of performance).

hamming_distance = (
Pipeline("karolin") # ('k', 'a', 'r', 'o', 'l', 'i', 'n')
.zip_with(lambda a, b: int(a != b), "kathrin") # (0, 0, 1, 1, 1, 0, 0)
.sum() # 3
