Since PEP-8 is specifically called out (and seems to be heavily influencing this document), do we want to develop brace/capitalization guidelines? PowerShell doesn't care, but it's often a big pet-peeve of developers, and I've seen a ton of different styles out there in the wild. Personally, I'm an OTB fan and, for PowerShell at least, I CamelCase everything since that's the Cmdlet naming convention.
