You're a few years late, as pretty much nobody agreed with me that the
operating system handling of it was plenty.
I think you misunderstand, we have etc.linux.memoryerror that can actually throw
an error on a null pointer using the signal handler.
Windows creates a exception, too, on null seg faults.
I have a suggestion: eliminate this feature, and add a -npe switch to the
compiler that errors on any null pointer usage. Asserts will be sprinkled in
everywhere, but may be useful to someone debugging a nasty null pointer segfault
somewhere.
It's just redundant to add these.
