Analyzing function foldr ...

  Trying degree: 1

== foldr :

  [['a; 'b] -> 'b; 'b; 'a list] -> 'b

  Non-zero annotations of the argument:
     10.00  <--  (*, *, [::(*)])
      3.00  <--  (*, *, [])

  Non-zero annotations of result:

  Simplified bound:
     3.00 + 10.00*M
   where
     M is the number of ::-nodes of the 3rd component of the argument

Analyzing function product ...

  Trying degree: 1, 2, 3

  A bound for product could not be derived. The linear program is infeasible.
