Less chance for spelling and copy and paste errors too if variable names are kept simple.

    True, but maintenance gets hard when they aren't evocative.

      Not so.

      Did you ever see music annotated with: "This_is_the_second_demi_semi_quavar_in_the_third_bar_of_fifth_stanza" (*).

      Or a resistor on a circuit diagram annotated: "This_is_the_470_ohmm_resistor_that_impedance_matches_the_output_of_the_third_stage_amplification_to_the_fourth_stage_feed_back_loop". (**)

      (*)I've no idea if that makes sense, but a musician would.

      (**)Ditto; but an electronics engineer would.

      Short variable names in context are just as clear to the maintanence programmer, and often more so, than long, overly descriptive ones--if the programmer has familiarised themselves with the purpose of the routine of which they are a part.

      And if he hasn't, he should not be maintaining the code.
