/***********************************************************************
test/null_uniqueness.cpp - Code for checking that null_type cannot be
converted to anything else. Because it triggers a compile-time
check, it can't be included in the test suite. You have to just
try building it. Comment out the assignment to int to check that
the return statement also triggers the compile-time check.
