if i accidentally make a typo and type something like

"Jimmy * 5

(i forgot the second quotation mark) then i get a compile error saying: unterminated string meets end of file. now if i correct this typo and press Enter again, i get:syntax error, unexpected tCONSTANT, expecting $end. over and over now matter what i put in there.
