I guess that'd work. > > (with-files-line-seq (file1 file2 file3) lines > > (take 10 lines)) > > The more idiomatic form would be [file1 file2 file3] > for the file arguments. Using (file1 file2 file3) other > than function calls is discouraged. Yeah, actually I was paraphrasing. The first arg is a coll and I probably did use a literal vector to pass it in. > > (with-files-line-seq (file1 file2 file3) lines > > (eager-seq (take 10 lines))) > > (with-files-line-seq [file1 file2 file3] lines > (doall (take 10 lines))) Meh.

Let's see. http://clojure.org/atoms firefox inc-search for "reset" Oops, not found. Sorry, the only way I'd have known about half of this was to actually read the api docs cover to cover, and for half of the other half, to download and install a third-party library and read ITS docs cover-to- cover. :) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
