* Unused variable 'file': using it also gets rid of repetition * No return value, when enum didn't match, from operator<<

An assert implementation that aims to provide usable information while maintaining as small a performance footprint as possible when not failing.
For binary comparisons, don’t just log the stringified expression, log the values of the two operands. For unary expressions, i.e. convertible-to-bool, log the value of that expression.
This should work without having to use separate macros for every comparison operator.
The compiler-generated code (assembly) should not branch to a distant site when the asserted condition is met. Preferably no branch at all should occur when the asserted condition is met.
No preparation of diagnostic information should happen at all when the asserted condition is met.
The largest performance impact permitted when not failing the condition is register spill-over. Specifically the register spill-over caused by the need to retain the values of the comparison expression is permitted.
TODO: Look into compiler optimizations capable of reconstructing the values instead of storing them.
Permit the user to override the failure handler.
It should stay
noexcept as well, although that should probably be customizable.
