I have found something a bit strange for me:
sage: xx=QQ(2)
sage: xx.parent()
Rational Field
ok...
sage: xxc=xx.sqrt()
sage: xxc.parent()
Symbolic Ring
Why not, but now:
sage: M1=matrix(QQ,1,1,[2])
sage: M1.parent()
Full MatrixSpace of 1 by 1 dense matrices over Rational Field
sage: M1C=M
This is a bug indeed:
