Much more influential in making object-oriented program- ming popular was Smalltalk-80, released in 198 0 as the result of research done in the 197 0’s ... The first way, often-used in object-oriented programming, uses inheritance. The second way uses higher-order programming. We will see that the first way is just a syntactic variation of...
