Well, it depends on the amount of code you duplicate, but in general by
duplicating code you're not removing code from user, you're adding it
and hiding it from user. In other words, the user will have to compile
your duplicated code and any other duplicates he may use directly or
indirectly. In the end, you made it worse for the user.
