const

Enable the expression "if (ptr)", while at the same time preventing "delete ptr" from compilling.

enable the expression "if (ptr)", see Alexandrescu "Modern C++ design", chap 7.8, p 178

This is done by providing an automatic conversion operator to the "Tester" class. The tester class itself introduces an additional "delete" function and thus makes "delete ptr" ambiguous. See Alexandrescu "Modern C++ design", chap 7.8, p 178
