Sorry, I just beg to differ. Of course, you should read a gentle
introduction into two-level-grammars beforehand (Cleaveland/Uzgaliz
excellent book on "Grammars for Programming Languages" comes to mind).
On the topic of ";"s: Icon programmers have to be careful about their
lexical/syntactical formulations anyway. The hamming distance between
formaly correct and in some way executable programs is rather short.
Any Icon programmer has to keep a steady eye on things like operator
precedendes and parentheses, correct spelling of identifiers, and more,
so I wouldn't see any ;-rule as another significant, additional burden.
This is not intended to deride Icon's syntax. Every bonus has its price,
and what is what is often in the eye of the beholder.
