[Python-ideas] String formatting and namedtuple

I've been experimenting with namedtuple, it seems that string formatting
doesn't recognize namedtuple as mapping.
from collections import namedtuple
Nt = namedtuple('Nt', ['x', 'y'])
nt = Nt(12, 32)
print 'one = %(x)s, two = %(y)s' % nt
# output should be:
one = 12, two = 32
currently, it is possible to use nt._asdict() as a workaround, but I
think it will be easier and more intuitive to be able to use namedtuple
directly with string interpolation
Sorry, if this issue has been discussed before.
