Enums and preprocessor macros are currently lumped together for coloring. Variables seems to include constexprs - which seems wrong to me. You cannot change the value of a constexpr - it's rather more like enum or #define than it is like a variable, static or local.
So I'd rather see constexprs and enum values handled with one common color, and #define could be that or could be its own thing. Either would work for my world.
But having constexprs as variables is just not-right. It's not really what they are (even const variables can be changed - have a memory address, whereas constexpr is little more than a type'd #define).
Again, I don't mind the #defines and enums having same color - small potatoes - but would prefer that constexpr get lumped into whatever bin the enums exists in - it's just a processor symbol - it has no inherent existence of its own.
