[Shootout-list] MLton - Sum of a Column of Numbers

[Raymond Racine]

(* MLton for sumcol *)
fun sumlines sum =
	case TextIO.inputLine TextIO.stdIn of
	    SOME str => sumlines (sum + (Option.valOf (Int.fromString str)))
	  | NONE => (print (Int.toString sum); print "\n")
	
val _ = sumlines 0

----------------------------------------------------------------------------

I was looking at the MLton SML, sumcol.sml failed test and noticed that
it was a bit parenthetical along with an extraneous eof check in the if
statement.  (Probably because of the change to the SML basis to 
TextIO.inputLine: TextIO.instream -> string option)

The above is more concise.
