Purists say there should only be one entry and one exit and anything else is obfu. What do you say?

It's a common idiom in many languages - so common it's listed in Fowler's refactoring book (Replace Nested Conditional with Guard Clause.)

It's a nice thick book - so you can always "re-educate" any purists you may find with it (apply swiftly to back of head :-)

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
