• Are there any data-binding solution that works in C++ and GWT and supports structures polymorphism?

  - by user116854

  I expect it should share a common description, like XmlSchema or IDL and should generate classes for target language. I found Thrift and it's really nice solution, but it doesn't support structures polymorphism. I would like to have collections of base class objects, where I could place instances of subclasses, serialize this and deserialize at the opposite side. Some mechanism of polymorphic behavior support, like Visitor, would be a perfect. Does anybody know something suitable for these requirements?

• Making one value "special"

  - by SplashHit

  What is the "computer science" term for the practice of assigning a special meaning to one of a type's values. For example a numeric variable called "amount_to_transfer" where the special value "0" means "entire account balance" or a date value "spouse_date_of_birth" where "1/1/1800" means "unmarried". I happen to feel that this is quite a bad "smell", but I'd like to have a name for it, and if possible, some blog post or article about why it's bad and how to fix it.
