Given the choice between using existing subprograms that may raise 
exceptions and writing new code to do the same thing but without raising 
an exception, I know of no circumstances in which the latter is an 
acceptable use of resources. I limit myself to professional software 
development; on a personal project you may waste your time 
reimplementing the entire run-time library for all I care.
