Description
While fixing bug #54 (closed) I ignored the Sparse module. I'm not even sure if there's anything to do, but the first place where to look is SparseBlock and other lvalue expressions, make sure that LvalueBit is not set when it should not be; then in the implementation of assignment, make sure that non-LvalueBit expressions are not writable.
