The default haskell mode with ghci has good defaults, completion systems
and an overall workflow which I can really work with. This is better
than the LSP system which uses a lot of memory and CPU without much
returns in comparison to this method.
When using the inbuilt RSS module, this becomes my personal config for
that module.
However, when not using that and instead using the newsticker inbuilt
for Emacs, I've got a config for that as well.
