<code>printf "%{"</code> is legal, and prints <code>%{</code>. With warnings on, it does issue a warning, but it's (currently) not illegal.
<p>
But your initial proposal talked about interpolating in strings, and in strings, "%{hash}" is currently fine. No warnings. I'd be more worried about regular strings 'breaking' than any (s)printf formats.
