Subject: [ruby-core:40779] [ruby-trunk - Bug #5571] Syntax Error when put String eql? with logical operation ("||") or "("&&")


Issue #5571 has been updated by Hiro Asari.


The || operator is binding the second test.eql? to "test", effectively turning the statement into

    test.eql? ("test" || test.eql?) "test1"
