5  Hilbert(9)[1:4,]  
6  throws an error because the result is not symmetric, but the result of  
7  subscripting a symmetric matrix does not need to be symmetric.  
8  Perhaps we should try to propagate the class to the subscripted matrix  
9  but, if that fails its test, fall back on a general matrix class.  
10  That is, the fallback class for dsyMatrix, etc. is dgeMatrix; the  
11  fallback class for dsCMatrix is dgCMatrix, etc.
