    Description

      Just call:
      Reflect.ownKeys(Math)

      That's cheeky but its not the only "special" object.  For example if you are just trying to figure out the "keys" for Math you can just do:
      Object.keys(Math)

      as that returns []
      But the same is true for:
      Object.keys(console)

      []

      But you can use:

      Reflect.ownKeys(console)
      [debug,log,info,...]

      So Reflect "can" work for special objects
      {{}}

       

      But in the case of:
      Reflect.ownKeys(Math)

      Qt will Assert in debug mode and crash will a nullptr dereference otherwise.
