    Instead, we reexport common and well-known things from `base` and some other
    libraries that are used in everyday production programming in _Haskell_.

-4. Export more useful and commonly used functions. [Hello, my name is Dmitry. I was

+4. Export more useful and commonly used functions.
    Things like `liftIO`, `ReaderT` type, `MVar`-related functions have unambiguous names,
    are used in almost every non-trivial project, and it's really tedious to import them
    manually every time.

-Whenever you want to allow a newer version of @text@ package, check:
-* The @text conversions@ benchmark, that the numbers with and without the rules
-are still the expected ones (see the comments there for what to expect).
-* You may optionally check whether any changes to `pack` and `unpack` functions
-and their `INLINE`/`NOINLINE` annotations took place.
-The current rewrite rules match with what happens in `text` package

-you can just check `git diff <that commit>..HEAD`.

-If these points hold, it should be safe to raise the upper bound on `text` version.

-If not, first do the necessary changes (preserving the backward compatibility),
-update the commit id above if you checked the code of the `text` package.
-Then bump the version constraint.
