We have a lot of code here. I think everyone agree that we need syntax highlighting.
Yes, there should be syntax highlighting for any code-related posts...
I'll use the rest of this answer as a CW sandbox... (Haven't fount the meta.SO counterpart yet)
Feel free to improve examples with more syntax, add other languages or correct mistakes, etc.
Testing code removed, syntax highlighting does not work on meta.
No, simply because we aren't here for fixing code. There aren't that many examples of code being used, with most questions being text.
