I just wanted to write "Not so". As much as I appreciate the OP in general, his knowledge of Algol 68 is limited. Algol 68 was more than the introduction of first class datatypes. Parallel programming comes to mind. In comparison to PL/I, there were other features such as automatic memory management. It helped to have had John McCarthy in the commitee.
