Clojure's spelling and Clojure's semantics. Repeated — #_#_ a b c — discards that many following forms, and that falls out of the recursion rather than being counted: the discard reads *a form*, and the form it reads may itself begin with a discard, so the outer one throws away what the inner one already stepped past. It belongs to read_form rather than to the sequence readers, which is what makes it work in every position a form can appear — top level, inside a list or a vector or a map, before or after a quote. The two loops that look for a closer or for end of input skip it as well, because a discard is not an element and a file ending in one has read everything there is to read. A trailing #_ with nothing after it is an error, and it is the same error an unterminated form already gives.
