You could try reading the command line before hitting Enter *wink*

I know what you mean, and it's a tiny annoyance for me too that when I 
type "help(function(" I have to delete the autocompleted opening 
bracket. So I guess that's a small annoyance a few dozen times a day.

But having the opening bracket auto-added is a small satisfaction, and 
if you're using the REPL for actual calculations and not just help(), 
the benefit probably outweighs the annoyance:

    # save up to four opening brackets
    result = function(myclass(arg)) + another(x).method()


So I don't think that have the extra complication of a switch to turn 
this feature off is a good idea.
