Yes, since the echelon form gets cached. There could be others (over
other rings), I just haven't checked. But doing a quick survey is on

Good, because this is a major bug! See below for how it could wreak havoc:
sage: A = matrix(QQ,2,range(4))
sage: C = A.echelon_form()
sage: C[0,0] = 20

You may recall some discussions some time ago about using WolframAlpha to make
comparisons with Sage results. Alex Ghitza in particular thought we might be

Happy New Year as well!
