display:not defined for class "double"

[Loris]

Hello, 

I found that octave display function cannot show the most of the data type. 
As example:

/octave:13> display 'pluto';
error: display: not defined for class "char"
error: called from:
error:  
C:\Octave\Octave3.4.2_gcc4.5.2\share\octave\3.4.2\m\general\display.m at
line 37, column 5
octave:13> display (10)
error: display: not defined for class "double"
error: called from:
error:  
C:\Octave\Octave3.4.2_gcc4.5.2\share\octave\3.4.2\m\general\display.m at
line 37, column 5
/

the same in matlab behave "correctly". 
/>> display 'pluto'
pluto
>> display (10)

ans =

    10/

Since I used display to print results in terminal window, I masked the
function, changing call for display in call to disp(). 

Question is.. is it a bug or an expected behaviour? 
Are there plans to fix it or make it behave like matlab in future? 

Thanks, Loris.
