Consider the following toy class in Stata:



class numbers 
double one = 0
double two = 0
double three = 0



I can create a new instance as follows:



.foo = .numbers.new

classutil describe .foo

numbers .foo:
double .one = 0
double .two = 0
double .three = 0


I can then drop .foo using the classutil command:



classutil drop .foo


However, if i try to just drop .foo.two, this is not possible:



classutil drop .foo.two
foo.two: can only drop top-level objects
r(459);


How can I drop a specific object that is not a top-level object?
