Wizards and Warriors

What Could Possibly Go Wrong?

Players, such as wizards and warriors, have weapons; such as staffs and swords.

So innocuously begins Eric Lippert's latest forage into object-oriented design. Like all of his best work, this adventure soon takes us into various intuitive dead ends and surprising ambush back-alleys. You will nod sagely as he overcomes each successive objection, excises each fly from the ointment, with a new design principle or approach; THEN CURSE as your newest paradigm rears up and bites you in the assets. Finally, you will marvel at the astonishing and enlightened conclusion of it all, by which time you will have become a better human being in every sense that matters (to an object-oriented software designer).

Note: the "DSLs" that emerge toward the end of Part Five are of course Domain Specific Languages.
