isa (operator)
isa is a keyword binary operator which tests the left-hand operator for membership in the type defined by the right-hand side. That right-hand operator could be a user-defined map (to which the left-hand side might belong via the __isa chain), or it could be one of the built-in types number, string, list, map, or funcRef.
__isa (map entry)
__isa is a special entry in a map that refers to the map's base class. It is part of MiniScript's support for object-oriented programming.
