Comment on Lens: Lenses, Folds and Traversalsparent

I agree strongly with this and take it one step further: I avoid the infix backticks that turn functions `into` operators.

But I'm not a hardliner. I do use backticks sometimes when building joins with Esqueleto and I do use a limited set of lens operators, like ^. and sometimes the %= variants if the situation calls for it.
