> From the google style guide:
> Normally, if a constructor takes one argument, it can be used as a
> conversion. For instance, if you define Foo::Foo(string name) and then pass a
> string to a function that expects a Foo, the constructor will be called to
> convert the string into a Foo and will pass the Foo to your function for you.
> This can be convenient but is also a source of trouble when things get
> converted and new objects created without you meaning them to. Declaring a
> constructor explicit prevents it from being invoked implicitly as a
> conversion.
> Implicit conversions should be the exception to avoid unwanted and unexpected
> behaviour.
