Hi,

I don't understand a point in the grammar :

5.4.6 AliasAssign:
    Identifier = Type

5.4.7 AliasReassignment:
    Identifier = StorageClasses(optional) Type

AliasAssign rule is included in the AliasReassignment rule.

Why there are two rules in the grammar to describe the same thing?

It seems that AliasReassignment rule is an orphan rule. Indeed it is not used anywhere else in the whole grammar.
