change 'constructor with 1 argument' to explicit constructor

* implicit conversion
The compiler is allowed to make one implicit conversion to resolve the parameters to a function.
What this means is that the compiler can use constructors callable with a single parameter to convert from one type to another in order to get the right type for a parameter.
