Conditional Baptism

Salvation through functional programming! The creator of this masterpiece has blessed us with the holiest of conditional statements—baptism implemented in Haskell. The function returns Maybe Person because even divine intervention respects type safety. If you're already baptized? Return Nothing. Otherwise, you get Just (markBaptized p). The conditionalBaptize function even uses monadic composition with maybe to handle the uncertainty of salvation. Next time your code needs saving, remember that even spiritual transformations can be expressed as pure functions with no side effects—except eternal life, of course.
