If one makes it a habit to think about how to name things, it will become easier. Copy-pasting is not fast if you factor in the time spent on problems because of it, even in the same coding session. One may not be sure of their intent, but they should have some intent. So at least reflect that one in the code.

I don't mean to be perfectionistic. There are certainly cases where “good programming habits” could be compromised. But people tend to excuse bad habits quite easily, without thinking of better ways.
