Yep, that would be good - keep everything local that can possibly be kept local.
There is at least one other single-letter function designator ("N") so the
chance of a conflict with other variables in a scene definitely exists. The
reason I had a collision with "K" is because I use the letter "I" to control
loops (short for "Index") then for nested loops I just keep going with "J," then
"K," et cetera. "N" is probably popular because it's the first letter of
"Number." There is no downside to using "#local" wherever possible, but there is
a benefit.
