I bought the APL book (https://www.amazon.com/gp/product/0471430145 https://www.amazon.com/gp/product/0471430145) several years ago (though it wasn't >$150 then) because I had a professor in college who loved to talk about APL I've opened it to skim a few times, and here's what I've realized: - purpose-built machines (and languages) are always better at their purpose than general-purpose languages/machines - I don't know nearly enough math for APL to [fully] make sense - a great deal of elegance and methods of thinking have been lost as languages (virtual (and physical)) disappear - flexibility is a wonderful thing in languages and hardware
