ProblemEven though Go is beautifully straightforward and blatantly obvious as to what is going on, there is still room for coding style differences.
And what happens when you're working in a multi-developer project not every developer uses the same coding styles?
- Use TAB character rather than spaces
- Use 2 spaces per TAB (v. 3 or 4 spaces)
