But both in the expressions:

>     let a = 1 in fun x -> 1
>     let a = assert false in fun x -> 1

the variable a is not used in fun x -> 1.  How can the type of x be
affected by an unused binding for a around fun x -> 1?

It also seems that assert false can be used polymorphically (because
of the relaxed value restriction?):

# fun () -> let a = assert false in (a 1, a true);;
