Summary: dict(key,values) initializer

Initial Comment:
Far too often I use the idiom dict(zip(keys,values)), or
the same with izip. How does letting dict take two positional arguments sound ?

Pros:
- Pretty obvious semantics, no mental overhead to learn and remember it.
- More concise (especially if one imports itertools just to use izip).
- At least as efficient (and probably more) as the current alternatives.
- Backwards compatible.

Sorry, the number of options for the dict constructor is already at its
outer limit.  No need to further complicate the situation in order to save
just five or six characters in the invocation.
