/**

   A convenience postfix macro that is equivalent to wrapping the

   preceding expression with User::LeaveIfError().

   The code:

   @code

   fs.Connect() OR_LEAVE;

   @endcode

   is equivalent to:

   @code

   User::LeaveIfError(fs.Connect());

   @endcode

   The implementation happens to rely on overloading operator|| for

   TLeave. However, this macro is not intended for use within general

   expressions, just to guard individual calls to methods that may

   return an error code.

/**

   Enabling overload for OR_LEAVE. Should only be invoked via

   OR_LEAVE, never directly.
