It’s not quite true that the compiler doesn’t care about white space. The lexer is part of the compiler, and it does care about white space. The semicolon insertion rule, in particular, pays attention to newlines. So, while the compiler doesn’t care about indentation at all, there are some brace/indentation styles that it will not accept. One of those is Allman style.
