-> and <- aren't replaced with → and ←

[erikkaplun]

If I've somehow missed how to turn it on in the configuration — I fully inspected the generated ~/.stylish-haskell.yaml to no avail — but it currently seems it's not possible to use stylish-haskell to convert -> and <- into → and ← respectively.

In fact, there are more examples like this, such as <= and >= not being turned into ≤ and ≥ respectively — I'm aware these won't compile without the import Prelude.Unicode import but stylish-haskell could also add that in the imports section (and possibly warn if the Prelude.Unicode package isn't available).

All in all, is it possible to customize stylish-haskell to support all or any of the above? Could it even possibly be added to the tool itself so that the above conversions could be enabled with a configuration flag?

I am also experiencing this issue, with commit a7200f5f1ee0d48aa6920f95251331efd4090c6a. I'd love to see this functionality.
