Seems a lot of people don't like the current behavior so much. ---------------------------------------- Feature #17104: Do not freeze interpolated strings when using frozen-string-literal https://bugs.ruby-lang.org/issues/17104#change-86950 * Author: bughit (bug hit) * Status: Open * Priority: Normal ---------------------------------------- ```rb #frozen_string_literal: true def foo(str) "#{str}" end fr1 = 'a' fr2 = 'a' fr1_1 = foo(fr1) fr2_1 = foo(fr2) puts fr1.__id__, fr2.__id__, fr1_1.__id__, fr2_1.__id__ puts fr1_1 << 'b' ``` Isn't the point of frozen literals to avoid needless allocations? But interpolated strings are allocated each time, so freezing appears pointless. -- https://bugs.ruby-lang.org/ Unsubscribe:
