With languages like Java, or especially C++,” Bornstein says, “abstractions can be convenient, but there 
are a lot of implicit operations that happen, such as when copy constructors are invoked, or destructors 
or assignment operators, or if you have any sort of operator overloading. Those implicit sort of function 
calls, unless you’re an absolute expert in the code base and know exactly how everything was designed, 
can actually create real problems when reasoning about a piece of code.
