Writing APL (or J/K) with the ascii character set is like coding C in Morse code. I wrote plenty of J code for my masters in particle physics and the only way I could use it without going insane was to write a noweb filter for literate programming when using latex symbols for the functions. The woven document was close to mathematics, the actual source code was editable source code.
