Why no from __future__ import formatted_string_literals in Python <3.6?
<p>We had <code>from __future__ import print_function</code> in 2.7, so could we have <code>from __future__ import formatted_string_literals</code> in, say, 3.4 and 3.5 (maybe even 2.7)?</p>

<p>Is there some policy that prohibits this, some technical reason, or just nobody got around tuit yet?</p>
