Syntactic experiments with arrays of functions and operators
J. Philip Benkard · ACM SIGAPL APL Quote Quad · 1984
The syntactic binding hierarchy of Benkard is refined to produce a numeric table. This table has been used by Bunda and Gerth to implement a syntactic model of APL2. The model is extended to include new classes of objects and strands of objects other than data. Directions for syntactic development are suggested, tending toward a language which achieves flexibility by nesting simple levels in a remarkable parallel with nested arrays. Cautious experimentation with models such as this one is urged before firm extensions are made to the language.
