ipython --autocall 2

    -autocall <val>
          Make  IPython  automatically  call any callable object even if you didn’t type explicit parentheses. For example, ’str 43’ becomes str(43) automatically.  The value can be ’0’ to disable the feature, ’1’ for  ’smart’  autocall, where  it  is  not  applied  if  there  are no more arguments on the line, and ’2’ for ’full’ autocall, where all callable objects are automatically called (even if no arguments are present).  The default is ’1’.
