CL condition system is based on error handlers, which is the 3rd paradigm aside from returning error values and exceptions. Unfortunately, it didn't really permeate the Unix based languages (C, C++, Java), because Unix had completely kneecapped implementation of error handlers in the OS (lack of user defined signals and their hierarchy). Error handlers are so much underrated that even books like Code Complete do not mention them. Each of the three paradigms has pros and cons in terms of code simplicity and runtime cost (in normal/error path), I don't think there is a clear winner.
