It's valuable to check your runtime values and to shut down the entire engine in case something doesn't match. This patch adds some magic plumbing to support a "panic" mechanism. A new "panic" statement gets transparently converted into a panic function and panic resource. The former errors if the input is not empty. The latter must be present to consume the value, but doesn't actually do anything.
