Pasting code in VIM is broken, here's the fix

Copying and pasting code snippets from other applications or a browser is du jour these days. If you're a VIM user like me, you've definitely run into the problem of Vim mysteriously inserting a lot of extra white space into pasted code. This is Vim being smarter than it should be - it thinks that you are actually typing and not pasting, so it proceeds to re-indent already indented code. The fix is simple:

:set paste

Paste the code in Insert mode, and once done, type the following command:

:set nopaste

Q.E.D.
