Abstract

Extended operator syntax, defined operators, and strand notation are evaluated as APL extensions using the concept of syntactic binding, which is equivalent to the function scope rule and is more readily extended to other classes of objects. Changing syntax has wider impact than adding function, and its side effects should be considered before adoption.
