Copy and paste itself is not the issue, but once the copy and paste orgy
starts you end up with more subtle bugs and silly differences than
copies. I spent enough time cleaning such crap up just to figure out
that once you've finished a full tree sweep you can start over.
grep for these things is a nuisance, but it's not rocket science to
figure it out. I rather have to figure that out than staring at a
gazillion of broken implementations.
