It is also a performance issue, since it requires constructing the RHS array even when it is never used (unless you are able to do various compiler tricks). I propose removing it. FYI, from 1.9 the Array for RHS is not generated if it is not needed. # not generated a, b = c, d a, b, c = d, e # generated a = b, c a = b, c, d I remain the spec because of compatibility. #=> go to matz issue. As you say the case which need to generate an array are not major case, it is not performance problem in my opinion. Thanks, Koichi -- // SASADA Koichi at atdot dot net
