Why not just show the out-of-range index?

    	On reflection I think my alternative suggestion might be just as 
good: the interpreter could indicate the character position within the 
line.  This also handles cases where the operands aren't simple names.  
(Not that I have any idea how much harder/easier this would be to 
implement.)

    	I ask for names and values because that is what I want.  If I have 
some expression containing a bunch of variables and an exception is 
raised, the most helpful information for me is the source code token 
that is causing the error, because I can see the source code in my text 
editor.  The value is not as important, because there may be many 
different variables that could be holding the same incorrect value.  I 
only want to look at the one that is ACTUALLY holding the incorrect 
value.
