As emacs user I often use emacs repl with ipython, but after update to ipython 5 I need to use --simple-prompt flag for my work. But when I try to create new def or class I get this error message

In [1]: def new():
  File "<ipython-input-1-ce93a60072ff>", line 1
    def new():
              ^
SyntaxError: unexpected EOF while parsing
