Precedence is what you’re missing. $ 6 'say 0 || 42 or 666' WARNINGS for -e: Useless use of constant integer 666 in sink context (line 1) 42 Why is that? Because the “||" is tighter than the “or”. So the above is equivalent to: $ 6 ‘(say 0 || 42) or 666' WARNINGS for -e: Useless use of constant integer 666 in sink context (line 1) 42 and then it should be clear why it is warning about the 666, because that is now used in sink context. For the “say” that is ok, but not for the constant. $ 6 ‘666' WARNINGS for -e: Useless use of constant integer 666 in sink context (line 1) Hope this made sense to you
