I wanted to learn APL and made some progress by writing semi-useful tools for a machine learning preprocessing pipeline using GNU APL (APL2). It was great fun and not too difficult; I just had to get used to the idea that the core data type is an array. Using the terse syntax made it feel very similar to writing mathematical notation in a student's maths class.
However, I felt that writing anything not closely related to solving mathematical matrix problems made no sense to me. Unfortunately, APL is too niche; I don't know anyone in my industry with whom I could share the tools. Nevertheless, it was a valuable learning experience.
