title: camelCase vs snake_case in C/C++ identifiers and filenames
body: <p>snake_case seem to be the convention in most of the C sources I've come across.
  camelCase is more comfy to type. Is there a good reason not use camelCase instead of snake_case?</p>
  
  <p>I think a source of problems might be that identifiers tend to "leak" onto the filesystem (like when you name a file after an identifier), and some filesystem might not handle case-sensitive names well. But is that still a thing on platforms of 2015 worth porting to?</p>
