[Python-Dev] [UPDATE] PEP 274, Dict Comprehensions (original) (raw)

+1 generally on dict comprehensions, but:

>>> print {1 for x in listofemailaddrs} {'barry@zope.com' : 1, 'barry@python.org' : 1, 'guido@python.org' : 1}

-1 on this bit. It's not at all clear what it should mean, and the saving over writing it out explicitly, i.e.

{x:1 for x in list_of_email_addrs}

is vanishingly small.
