> 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.
