I always thought this referred to abstract computer science concepts like : constant vs literal vs variable, scope, composition vs aggregation, encapsulation, function, procedure, polymorphism, interface, loops, accessor, mutator, class vs object and instantiation, abstraction, linked lists, arrays, hash (not so much hash), recursion, etc. I consider these names to be beautiful and succinct and a lot of thought was put into them.
