Not really. We want them to be fast. They are intended for use in main loops only and if you look into the code you'll see that we don't even check whether they are actual integers. The programmer should care about that...
I agree on what you say. This is even stated in the documentation.
What I am saying is that, instead of writing "Not a 32-bit integer..." and exiting, you could throw an exception. This would not impede performance, since the test now controlling the printing would then control the throw. The change I am proposing would make debugging much easier and would make possible recovering from the error (and this is the thing that is very important to us). All the best
