Basically, you can implemente it with a tree. Each node in this tree
corresponds to a scope and contains the declarations in this scope.
When you search for a declaration, you begin with current node in the
tree, if you do not find it, you continue in the parent and so on.
In practice, nobody would like accturally maintain this tree, they use
a stack to keep a path from the root to current node of this tree.
