An example of a situation where a developer is limited by constructor rules

DBConnection_NoCompile.cs

// this class doesn't compile!
public class DBConnection
{
  public DBConnection(string pConnectionString, bool pIsTransactional)
  {
    // do something mind-blowingly awesome
  }

  public DBConnection(string pConnectionString, bool pKeepAlive)
  {
    // this would do something awesome if the compiler wouldn't complain!
  }

  // ...
}
