no to my knowlege that doesnt exist. i dont think it ever will either as it logically would make no sense. trying to create an array of things that could be of many varied types would be impossible let alone trying to use that data in any practical way. imagine a get all variables that consisted of: a int, a string, a character class, mesh, map of ints, and an array of names, that would be weird right. also theres nothing you could do with the data at that point, you cant get a value of character, you cant get index 1 of a single variable, you cant read a character like a string. it just makes no sense.
i dont know your situation or use case but you may want to look into using a struct for your data. a struct can contain many variable types but it is predetermined and you can access each one as need be.
