 // ThrowError is a convenience function. Many times a user error is an 
 // exceptional case that requires major control flow. We use exception
 // handling for that. This lets us aboid having to check for error cases 
 // all over the place.    
 //
 // If an error is more of a casual observation that doesn't really get in our 
 // way but will ultimately fail CodeGen, then use PrintError instead of ThrowError.

//-----------------------------------------------------------------------------
// Blue has a single unified error subsystem, with error codes & checking
// partitioned across the different sub-systems.
//
// All users errors (ie, resulting from incorrect source file) must create
// a ErrorException object and send it through PrintError.
// This ensures standard error reporting & tracking.
//
// Note that this does mean that we have to create an exception object for
// every single error. This is ok because errors are rare. It is more 
// important to have strong (robust & flexible) error handling then fast
// handling.

        // ErrorException and then they come through here.
