or that it doesn't have to be used with `const` most of the time.

@ -89,8 +89,8 @@ Summary:
- `class SomeClassName`
- `enum IPCCommandType`
- All compile time constants should be fully uppercased. With constants that have more than one word in them, use an underscore to separate them.
- `const double PI = 3.14159;`
- `const int MAX_PATH = 260;`
- `constexpr double PI = 3.14159;`
- `constexpr int MAX_PATH = 260;`
- All variables should be lowercase with underscores separating the individual words in the name.
- `int this_variable_name;`
- Please do not use [Hungarian notation](http://en.wikipedia.org/wiki/Hungarian_notation) prefixes with variables. The only exceptions to this are the variable prefixes below.
