We are aware of the problem - strange that this observation comes from 
you - who essentially proposed this syntax [1] :-)
I think that the only problem is with cast expressions (where there is 
an ambiguity between parenthesized expressions and cast to a disjunctive 
type) - I don't think an expression of that kind can occur in a context 
where a variable declarator could be expected, am I wrong?
