some code cleaning and complexity improvements (#7133)

* do not use `and` for non mutually recursive types

* use List.init, fix complexity of a few operations and make some code
more readable

* explicit some parameters to make working without LSP/Merlin easier

* use fold_left instead of filteri because it is not available on old
OCaml versions
