I've been following this discussion with puzzlement. Assertions can be wonderful tools when debugging (usually during unit test). But the most important feature of pragma Assert is that it can be turned off globally in production code.
If there are Booleans which do need to be checked at run time, for example when validating inputs, those checks often should have a tightly wrapped exception handler, and certainly should not use pragma Assert.
I would consider it a major bug to have a pragma Assert that could fail at run-time absent a hardware failure or some such. (Even though it would be turned off in production code.)
