Moving the argument of CProdN/CLambdaN from binder_expr to local_binder_expr.
The motivations are:
- To reflect the concrete syntax more closely.
- To factorize the different places where "contexts" are internalized:
before this patch, there is a different treatment of `Definition f
'(x,y) := x+y` and `Definition f := fun '(x,y) => x+y`, and a hack
to interpret `Definition f `pat := c : t`. With the patch, the fix
to avoid seeing a variable named `pat` works for both `fun 'x =>
...` and `Definition f 'x := ...`.
The drawbacks are:
- Counterpart to reflecting the concrete syntax more closerly, there
are more redundancies in the syntax. For instance, the case `CLetIn
(na,b,t,c)` can appears also in the form `CProdN (CLocalDef
(na,b,t)::rest,d)` and `CLambdaN (CLocalDef (na,b,t)::rest,d)`.
- Changes in the API, hence adaptation of plugins referring to `constr_expr` needed.
