But a slight modification of the code seems to reveal the following:  
Although a variable and a scalar can both have the same name (for  
example, -b- in Austin Nichols's exammple), it appears that a matrix  
and a scalar cannot have the same name. Is this correct? See what  
happens below when I try to -matrix list- b after scalar b has been  
defined.

[P] index has an entry "namespace and conflicts, matrices and scalars"  
pointing to [P] matrix. The second page of [P] matrix contains a  
heading "Namespace" that explains that matrices and scalars share the  
same namespace.
