Is there an equivalent to C++s default values for function arguments?
Default arguments are not supported but you can attain the same effect through function overloading. The reason we prefer overloading as the solution to this problem is that it allows you, at a later time, to change the default value of a parameter without having to recompile existing client code. With C++ style default values, the defaults get burned into the client code, and you can therefore never change them once you’ve published an API.
