That was what I was thinking, then I saw that this will stringify enum values, eg. nameof(c) returns "RED", which the preprocessor #x will not do.

To be sure: nameof(c) returns "c" (nameof return name of variable) nameof_enum(c) returns "RED" (nameof_enum return enum name of enum variable)

I only use STRINGIZE for error messages. I learned about it from reading the source for assert macros.
