Reddit discusson thread.

I made a way to get more free stuff and free stuff is good.

The current implementation of deriveVia is here, it works with all the examples here. Needs GHC 8.2 and th-desugar.

It doesn't take long

for new Haskellers to get pampered by their compiler. For the price of a line or two the compiler offers to do your job, to write uninteresting code for you (in the form of type classes) such as equality, comparison, serialization, ... in the case of 3-D vectors
