Comment (by Sergey Fedoseev):
Replying to [comment:3 Дилян Палаузов]:
> I know that iterating over a {{{dict:}}} and {{{dict.keys():}}} is
effectively the same, but while the later returns (an iterator of) a view,
I don't know what the former returns and therefore whether both forms are
really equivalent.
{{{
In [2]: iter({})
Out[2]: <dict_keyiterator at 0x7fd09e6d3598>
In [3]: iter({}.keys())
Out[3]: <dict_keyiterator at 0x7fd09e6d3728>
}}}
