Perhaps this has been brought up in the past but I couldn't find it in
the archives: 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 as the current alternatives.
- Backwards compatible.

Cons:
- ??
