The bottomup parameter in callbacks will be calculated for all parameters
of call`` expressions. The parameter to the callbacks are thus a list of lists. This function merges these lists into one that contain a list for each named component in the bottomupparameter. If results are not named in thebottomup` list, they are discarded.
merge_bottomup(bottomup)List of bottom up analysis results.
The vectors from bottomup are concatenated, so one level of lists
will be flattened. Use more lists, like list(list(2), list(3))
if you want to prevent this.
