actually, everthing which causes a 'syntax error' in that situation, 
e.g. if you type something like:

 > f((a)
+

(where there is a second opening parenthesis), you could enter 
everything which  would _not_ be aloud syntactically after the closing 
paranthesis (e.g. a "=", any number/letter, a brace, ...).

but if one of the developers stumbles over this: there _should_ be a 
clean way to get out of the loop (I seem to recall that ESC worked once 
upon a time ..), right?
