Sage consider 1D symbolic expression as "sage symbolic expression" but in higher dimension it considers it as a bool.
%var x,y ex = [[x^2+y],[y]] == [[0],[1]] type(ex) gives <type 'bool'> while ex = x^2+y == 0 type(ex) gives of course <type 'sage.symbolic.expression.Expression'> Wouldn't it be useful to be able to create sage symbolic expression with vectors in order to solve them (without writing each expression independantly) ?
