When not in release mode, accessing an out-of-bounds element in an array throws a RangeError.  I would like to do the same thing in dcollections when indexing, but the only tool I know of that enables throwing an error in non-release mode is assert, and that only throws an assert error.

Does anyone know how to throw an arbitrary exception on an error when not in release mode?

Untested code. Also, horrible:

void throwInNonRelease( T = Exception )( lazy bool test, lazy string msg ) {
  try {
    assert( test );
  } catch ( AssertError ) {
    throw new T( msg );
  }
}
