> Correct, once a compiler error is thrown, it is too late to magically
convert that into a run-time exception. I am indeed talking about a
conditionally compiled macro(s), which would statically assert, or generate
a run-time exception, depending on a pre-processor defined flag.

capability. I had not considered the convenience of debugging an actual
run-time call stack vs. the compiler trace. I will design this library so
that by setting a single breakpoint in the library, it will always give
access to the call-stack leading up to the failed assertion.
