Lisp syntax rarely make the first element optional, and in this case it's both the first and the last one:
(dotimes ([VAR] COUNT [RESULT]) BODY...)
which is a bit alien, and it's perhaps not worth the trouble for just omitting an underscore?
> (dotimes count ...)
That wouldn't allow for arbitrary expressions so it's of limited utility (and Lisp-alien, again). There's also the risk that someone will eventually replace a variable by a function call, turning (dotimes x ...) into (dotimes (f x) ...).
