Oh, you mean actual Numeric typecodes, not Numeric-like typecodes :-)

dtype(obj).char will not work for the Numeric typecodes that changed, 
set up a dictionary-like object which uses dtype(obj).char on all but 
the ones that changed is my suggestion.   See the core/numerictypes.py 
module for dictionary-like objects.   Perhaps this would be a good thing 
to add to numpy/oldnumeric


'b' --> 'B'
'1' --> 'b'
's' --> 'h'
'w' --> 'H'
'u' --> 'I'
