Module Notation_term
notation_constr
notation_constr is the subtype of glob_constr allowed in syntactic extensions (i.e. notations). No location since intended to be substituted at any place of a text. Complex expressions such as fixpoints and cofixpoints are excluded, as well as non global expressions such as existential variables.

Note concerning NList: first constr is iterator, second is terminator; first id is where each argument of the list has to be substituted in iterator and snd id is alternative name just for printing; boolean is associativity

Type of variables when interpreting a constr_expr as a notation_constr: in a recursive pattern x..y, both x and y carry the individual type of each element of the list x..y
type notation_var_binders = Names.Id.Set.tThe set of other notation variables that are bound to a binder or binder list and that bind the given notation variable, for instance, in "{ x | P }" := (sigT (fun x => P), "x" is under an empty set of binders and "P" is under the binders bound to "x", that is, its notation_var_binders set is "x"
