Re: Further revision of Oberon-07

That is a pity - I would have found it useful.

Another change is the removal of constant parameters. In Oberon-07/11 non-scalar value parameters can not be assigned to and are passed as constant references. This is a great move I think as the constant parameter was only introduced as an optimization feature. It is also interesting to note the as...
