One person wouldn't use multiple styles, a big team of developers, it's different story.
Imagine in real big project, when you hire consultants to work on part of a project, and they write their code in a different style than that of the team, which they are using for months, and then you need to debug that code - I have been there multiple times with my consultants, mistakes happen out of habits. @araq and @dom96, maybe a tool would solve the problem, like an option in fmt that says reformat all identifiers into a certain style, this way code can be imported and transformed into one single style. One problem with my suggestion. It's easy to convert between camel case myVar and snake case my_var, but not when it's not obvious myvar, since these all are the same variable. The funny part, I saw the vote on twitter, and by mistake voted "Yay" XD
