> their main drawback: k/q (like clever regexes) are often write-only code This depends on the code reader's mentality. One line of k (or q or j or apl) would do what 10 lines of verbose languages do. For verbose languages, your expectation is spending 1 minute for 10 lines of code to fully understand it; but for terse languages, you need to change your expectation to spending 1 minute for only 1 line of code. You are not going to understand anything if you still want to spend 6 seconds per line. On the other hand, proficiency is important. You read English articles in a slow pace in your first grade; you are not going to be a speed reader without practice, even if English is the only language you speak. No one would expect you to speed read Japanese right after you can compose simple Japanese sentences.
