Bug #14624: #{nil} allocates a fresh empty string each time
https://bugs.ruby-lang.org/issues/14624
* Author: bumblingbear (Dillon Welch)
* Status: Open
* Priority: Normal

* ruby -v:
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
This causes a bunch of unnecessary string allocations in the following scenario: "#{'rails' unless boolean_condition} is great". Each time this line is called when boolean_condition is true, it evaluates to nil and when nil is interpolated into a string it allocates an empty string. Ideally, the behavior of nil.to_s would reference a frozen empty string that wouldn't need to be reallocated each time.
