- Add mapping for ValueMapper for T* - Have to register basic types so that they can be passed as UserObject refs. Not ideal. - Refs have ambiguity.

Sorry for the delay, been busy doing other things. I'll try and investigate. |

Thanks. I have been using the fix that I uploaded for review and it serves me well in the mean time.-Shie-reiOn Nov 12, 2020 6:18 AM, Bill Quith <notifications@github.com> wrote:

This fix makes passing a pointer to std::string, integer or float typed argument to a metaclass function possible. This is necessary in order to be able to use a function argument to return the result from a function. I think PONDER effectively casts a pointer argument to any type to a pointer to UserObject. Because of this, the basic type needs to be registered as a PONDER_TYPE and be declared as a metaclass. For example, if you have a pointer argument to int in a metaclass function, you have to add
PONDER_TYPE(int) and ponder::Class::declare<int>("int")in your code. The fix in this pull request is to make sure that after the registration and declaration, the ponder::Value for an 'int' type variable can preserve its ponder value kind as a number kind instead of a User kind. The same goes to a string or a float.
