Description of Change(s)
enum.h
are replaced by simply passing the variadic arguments asstd::string
arguments. If there are no arguments, the macro expands tostd::string{}
which is the empty string (and equivalent to the default argument). Otherwise, the variadic arguments will be passed to thestd::string
constructor.scopeDescription.h
are replaced with variadic templates. Forwarding overloads are provided for common string types to avoid needless construction of a new string when no formatting arguments are provided.Fixes Issue(s)
