I'm guilty of this, and I wouldn't have it any other way. I have some short-term memory issues, and I cannot follow modern programming practices where there are 20 different files each with a separate part of a class within them 20 folders deep because folders were used as a naming convention for some GOD AWFUL fucking reason.
This fucker programs so well that they don't even need a linker. There's only one O that matters and that's Oprah, so we make sure that our projects only have a single .o in them as well!
