 ### Function Names
 * We use 
[lowerCamelCase](http://en.wikipedia.org/wiki/CamelCase#Variations_and_synonyms)
 for function names (Google uses mixed case for regular functions; and their 
accessors and mutators match the name of the variable).
-* Leave spaces around overloaded operators, e.g. `operator + (...);` rather 
than `operator+(...);`
 
 ### Namespace Names
