Good languages actively fight off poor programming. Take ML or Haskell: if you didn't think about the problem well enough beforehand, it won't compile.

No, but in the right language, you can at least be shielded from the monkey-patching.

But you need trained programmers to use the right language.

Also, Python is clearly a step up from English on a variety of metrics, including the reduction of the ability to monkey-patch.

Functional languages can do even better, however.
