When you build overloaded modules, you spend more time in design and implementation than you might with separate, standalone modules. This additional up-front time will be repaid handsomely down the line in program productivity and ease of use. 1.When to Overload? When you overload, you take...
It can lead to many ambiguous sets, if you don't design your overloaded function sets with extreme care.Athugasemd Ambiguity of overloaded functions can't be determined until a function call is encountered. At that point, the sets are built for each argument in the function call, and you ...
There is a precedent in language design when something advanced is reserved to the standard library, or built-in functions, only. One such example is generics in Go language. It's a path to consider with regard to overloads. There is a lot of demand to keep the language simple, and sh...
contains more than one function, the overloading is ambiguous and generates an error. The function that's eventually selected is always a better match than every other function in the group for at least one argument. If there's no clear winner, the function call generates a compiler error....

If I'm wrong about this. Please let me know. If I'm right, then I think this is an issue, since in languages like C++ or JAVA a no arguments overload is valid. Thanks! Member DanielRosenwassercommentedNov 14, 2015 how would I know about overloads otherwise?
language designpreprocessornotationproblem domainsThis paper presents a practical method of adding problem-specific notation to an established computer language. Our idea is to use unrestricted operator overloading as a tool to map the problem domain notation directly into an existing programming language...
I must say that overloading operators without saving their semantics is a bad design. In your case it would better be a functionswapNames(tmp1, tmp2)ortmp1.swapName(tmp2) May 10, 2013 at 3:38pm closed account (DEUX92yv) As far as an IDE, I recommend at least TRYING Visual Studio...
In order to determine what member function to call, the compiler considers the following two options: // the definition for x being on the left:x.opBinary!"op"(y);// the definition for y being on the right:y.opBinaryRight!"op"(x); ...
This is standard behavior, but it's required by the compiler. The HSV class included the same set of comparison operators, so I'll let you investigate those in the sample project.The overloaded = operator methods rely on the overloaded Equals method, which comes in three varieti...
