It's the call to possible "operator &&()". You can look at the test for example. I met the problem before, roughly 2~3 years ago. But I thought this is  problem of user codes that time.

But now I realized it was super weird to override the behavior of '&&' or '||' in fold expression. So I decide to send this.
