## Const as Much as Possible
`const` tells the compiler that a variable or method is immutable. This helps the compiler optimize the code and helps the developer know if a function has a side effect. Also, using `const &` prevents the compiler from copying data unnecessarily. The [comments on `const` from John Carmack](http://kotaku.com/454293019) are also a good read.
