I open to that.

For this time being, let's do this.  Add itertools.izip_longest() in 
Py2.5 and include a recipe for izip_exact() and see if anyone cares 
enough to ever use it.  The new any() and all() functions started out as 
recipes and graduated when their popularity was shown.  If izip_exact() 
proves its worth, then I would be happy to add it as a tool.
