HIR Visitor refactoring
This change split the single HIR visitor in smaller abstract ones:
- Stmt
- VisItem
- Pattern
- ExternalItem
- Impl
- Type
- Expression
Instead of providing a Base class with empty visit() methods, they are kept
abstract to avoid the case where a missing visit() is silently ignored:
implementors must explicitely override all visit.
There is also a FullVisitor that covers all HIR nodes and also provides a Base
class with empty behavior.
fixes #825
