How much time has been wasted on the Tab vs spaces question? ...wait ... I bet by just mentioning tab vs spaces you are already starting to take sides. Getting your facts straight. Preparing for that long brown bag lunch where you argue that tabs give developers choice. Choice to see how deeply indented to view code. Choice on how much screen real estate to use. Developers need choice. By using spaces you are taking away developers' freedom. Freedom lovers use tabs!!
Everytime somebody writes a coding spec that discusses tabs versus spaces time is wasted that could be better spent doing something else. I want my language to make some decisions for me about syntax so I don't have to waste time thinking about it. TIMTOWDI forces me to think about what syntax to use. It opens up doors for pointless discussion on coding style. It makes me less productive.
