APL is a powerful language for program architecture, as demonstrated through a comparison of brainfuck implementations. The code transitions from a procedural v0 to a data-first v1 paradigm, emphasizing the importance of efficient state updates and input/output handling for improved performance. The v1 architecture allows for potential instruction fusion and parallel execution, breaking free from the constraint of executing only one instruction at a time. This discussion on architectural differences touches on deep topics beyond a toy implementation, with implications for more serious projects. Adám Brudzewsky’s feedback and expertise in APL were invaluable in refining the code.
