Was just scrolling through the docs. Does anyone feel comfortable with all these generic type annotations? I'm not expert programmer but this looks overkill to me.
This is also one of my favorites, but it can get even more verbose. However this is how the go type system is designed to work with covariance. Without the `~` operator these functions could only be used for a much smaller range of inputs.
But this complexity is an implementation detail of the library, you do not have to understand it as a user of these functions. From my perspective it is a valid approach to move complexity from use application layer into the library layer, so it can be hidden there and tested once.
