But that goes here too. You can write software with Java knowledge from school. But doing things efficiently for your goal (large data sets, real time processing etc) requires skill. How is that different than Java (or Python, or C++); if you do things in your 20 unnamed functions, your software will most likely not be pleasant to read or execute. And the 'unnamed' is really not true; you are tripping over the fact that these are symbols, but these symbols do have names in APL/j/k. And, like learning a new natural language, you really do not need that much time learning them. All languages have this issue, the symbols is not the difficult factor here. If I do not know dictionaries are called dictionaries/hashmaps, my Python code will likely end up a horror show.
