Remove the forward class hint feature.
It was not documented, not properly tested and thus likely buggy. Judging
from the code alone I spotted already one potential bug. Further more it was
prominently making use of the infamous "arbitrary term as hint" feature.
Since the only user in our CI seems to be a math-classes file that introduced
the feature under a claim of "cleanup", I believe we can safely remove it
without anyone noticing.
