+%%% If a function is removed from a module and the module has previously
+%%% been added to a PLT, the function will not be removed from PLT when
+%%% the PLT is checked. This results in dialyzer failing to produce a
+%%% callgraph warning when doing success typings analysis if the remove
+%%% function is still called in another module
+%%% As the function is not removed from the PLT a prior warning, such as a
+%%% contract types warning, might be emitted when the removed function
