Subject: [PATCH 3/5] response: avoid garbage string entirely
Date: Sat, 21 Nov 2015 08:52:30 +0000
Message-ID: <20151121085232.23086-4-e@80x24.org> (raw)
In-Reply-To: <20151121085232.23086-1-e@80x24.org>

Even in frozen string literals enabled in Ruby 2.3.0dev,
dstrings still create garbage as the optimizer is
not yet smart enough to optimize it despite the limited
choice of internals being known.

Maybe in the future Ruby will be smart enough, but not yet...
