True, but if the language did it, it could deal with it in a manner which 
compiled out the try-catch in -release mode as well as avoid the ugliness of 
wrapping the whole function body in a function call. Still, it would probably 
be better if we could get the compiler to recognize the idiom and compile out 
the try-catch in that case rather than adding something like that to the 
language. But I don't know how reasonable that is.
