dict comprehension

[Daniel Fetchinson]

Hi folks,

There is a withdrawn PEP about a new syntax for dict comprehension:
http://www.python.org/dev/peps/pep-0274/ which says:

"Substantially all of its benefits were subsumed by generator
expressions coupled with the dict() constructor."

What does the author mean here? What's the Preferably One Way (TM) to
do something analogous to a dict comprehension?
