The #defines in project/EsmScriptFuncs.cpp could also remain short with the long defs as a comment. Although they do seem to be quite at home in EsmScriptDefs.h, in case of being used elsewhere. Using static constexpr might be a thing, macros are cheaper in the preprocessor – there may only be a minimal difference.
