akkartik, here are the results.

  Use (quit) to quit, (tl) to return here after an interrupt.

I think rocketnia has figured it out. Does rocketnia's comment http://arclanguage.org/item?id=19137 make sense? Basically you shouldn't get an error if you type in this expression character by character, but you should if you paste it into an arc session without a trailing <enter>.

  (def read-all2 (filename)
    (w/infile file filename))
(Try it out each time as before by running (read-all2 "Log.txt"))

Thanks for that.

It does appear that the problem is with pasting into the repl. So, how does one hook up arc with Emacs?

Thanks to all those who chimed in with help. Great community here.
