You've used only some pretty lame languages, then.
Yes. And?
I don't always get the choice to use a non-lame language. ;)
Embedded hardware, for example, forces me to use a lame language quite

Anything with preconditions and postconditions (i.e., "design by

codes specifically can't be used to replace.
Correct. I consider both exceptions and return codes to be specific
cases of what can be done with closures and continuations.
