Document function limitation of var properties

Functions cannot be assigned to var properties due to the fact that
such an assignment signifies a binding assignment.  This limitation
needs to be documented.  One workaround is to assign an array which
contains a function element to a var property, and this commit also
adds a unit test to ensure this works.
