For example if someone sent the message
“I fucking love XML”
and you replied
“It is horrible”
Your reply is only valuable so long that it can easily look up the original message for context. Which means it’s not likely to be shared or boosted because your reply is an incomplete message.
If you changed your reply
“XML is horrible”
You are no longer using a pronoun to reference the concept of XML and anyone who knows the rust borrow checker can appreciate why this is good practice.
