== Goals

* Avoid all partial functions (like @head :: [a] -> a@). The types of
partial functions lie about their behavior and usage of such functions can
lead to the unexpected bugs. Though you can still use some unsafe functions
from @Relude.Unsafe@ module, but they are not exported by default.

* Type-safety. We like to make invalid states unrepresantable. And if
it's possible to express this concept through the types then we will do it.

* Performance. Prefer Text over [String], use spaceleak-free functions
(like our custom sum and product).

* Minimalism (low number of dependencies). We don't force users of
relude to stick to some specific lens or text formatting or logging
library.

* Convenience (like lifted to @MonadIO@ functions, more reexports). But
we want to bring common types and functions (like containers and
bytestrng) into scope because they are used in almost every application
anyways.
