Warning for shadowed variables

[kernie]

Hi,

wanted to report that I compiled a project that is based on nlohmann::json v3.10.4 and it used -Wshadow with the GNU g++ v7.5.
During compilation I see

json/single_include/nlohmann/json.hpp:18813:5: warning: declaration of 'count' shadows a member of 'nlohmann::basic_json<ObjectType, ArrayType, StringType, BooleanType, NumberIntegerType, NumberUnsignedType, NumberFloatType, AllocatorType, JSONSerializer, BinaryType>' [-Wshadow]
     {
     ^
json/single_include/nlohmann/json.hpp:22078:15: note: shadowed declaration is here
     size_type count(KeyT&& key) const
               ^~~~~

Maybe worth looking into...
Thanks
