+%%---------------------------------------------------------------------
+%% Module that went into an infinite loop when trying to assign types.
+%%
+%% What was happening is that for functions which are in an SCC but all
+%% return none(), a second chance was given to them by the analysis to
+%% see whether they return none() because they are involved in an loop
+%% (presumably server-related) and could be assigned the type unit()
+%% instead. The problem is that when the really return none() for some
+%% other reason (an error such in this case) then we will again find
+%% none() and try again for unit(), thereby entering an infinite loop.
+%% The issue was resolved on May 17th by adding an appropriate boolean
+%% parameter to dialyzer_typesig:solve_scc() function.
