9. As of now, values are not named, whereas I believe they are in debugger.  IE given def f(a,b,c): 1/0; f(1,2,3), viewer prints unlaabelled 1, 2, 3 on separate lines.

Also, the representation of a value may not fit on a line.  I believe a current debugger patch addresses this issue.  Clearly, there should be one function for displaying locals and globals.  And in debugger, one should be able to display them for previous frames.
