(* - if PRec (_, names, arities, bodies) is in env then arities are
   typed in env too and bodies are typed in env enriched by the
   arities incrementally lifted 

  [On pourrait plutot mettre les arit�s aves le type qu'elles auront
   dans le contexte servant � typer les body ???]

   - boolean in PApp means local turn off of implicit arg mode
   - option in PHole tell if the "?" was apparent or has been implicitely added
