FWIW, it sounds like a good idea to me.
Another use I can see in this is when you are worknig on a certain portion
of your program that you haven't actually included any calls to yet - at
compile time the compiler will still have a cry if there are errors in
this code, even though it isn't being used. An option like this would
allow you to get around this and generate the executable, anyway. (And I
imagin that since the code with errors is never called, the exception will
never be raised. That code probably would [should] get optimised away,
anyway)
