I see a theme here. There are many Clojure functions that take an argument that must be some kind of sequence where it is frequently the case that only a single value is needed. Is the main reason that these don't support passing either a single value or a sequence that the overhead of checking that would hurt performance? Here's another example where this theme makes the code look a bit complicated. (use '[clojure.contrib.str-utils :only (str-join)]) It would be great if this could be written as (use '[clojure.contrib.str-utils :only str-join]) or even (use 'clojure.contrib.str-utils :only 'str-join) It's not clear to me why the use function couldn't figure out what to do with these simpler arguments. -- R.
