Hi,

it would be more consistent to either avoid using aff_combination functions
in get_computation_cost_at completely, or rewrite it to use aff_combination
instead of the current difference_cost/... functions (however, the latter
would probably lead to somewhat slower compilation time). The patch should
also include a testcase for the problem.
Thanks for working on this,
Zdenek
