Hi D developer, Any plan to support this really cool feature of Multiple type return value? http://golang.org/doc/effective_go.html#multiple-returns
In Java and C++ we need to use the HashMap to do this and does not have compiler checking and need runtime casting checking? func (file *File) Write(b []byte) (n int, err Error) // different type. func nextInt(b []byte, i int) (int, int) // same type func nextInt(b []byte, pos int) (value, nextPos int) // same type. These ability in D will be useful to reduced the amount of extra runtime casting and checking a function. I am aware of this in/out parameter like in the MS SQL/PL/SQL. However that would meant that I would need to create all those variables in stack before I call updateRow. //void updateRow(int out myNum, string out myStr); Where else if D allows : // function updating the collection table and returns the number of rows updated and also all the keys updated. (int changeCount, string[] autoId ) updateRowA(int myNum, string myStr); That would allow the caller to only create the variable needed in the stack post calling the updateRowA. Hope this is a good idea? Please share what u think. Matthew Ong.
