I've always been a big fan of this underused language feature.


I hope that the next generation of Novell's C++ compiler will make some use
of dynamically-valued constants in optimization.


Ada also has dynamically-valued constants. I know for a fact that
optimizations making use of them are in some of DDC-I's Ada compilers.
The optimization is easier in Ada because you know the constant object
can't be aliased.
