Explore a 25-minute conference talk from Dyalog '23 that delves into the implementation of APL Array Notation. Learn about Kamila Szewczyk's journey in discovering APL and her internship experience at Dyalog Ltd. Gain insights into the advantages and uses of array notation, including its static parseability and "fast execute" mechanism. Discover the challenges of serializing APL objects and the development of a new C-based serializer. Examine the automatic numerical differentiation system function, including derivatives of dual numbers and complex derivatives. Conclude with an introduction to the reverse compose (behind) operator in APL.
