The "big bang" sometimes happens to me when I write in Haskell. After I fix all the compiler errors, of course. I just wish there were a language with a type system that can detect almost as many errors as Haskell's without having quite such a restrictive, bondage-fetish feel to it.

But yeah, in general, only trivial programs work the first time you run them. That's a good definition of trivial, actually.
