Just a suggestion, how about a 'DeclContext' AST class that FunctionDecl 
would inherit from (and NamespaceDecl, RecordDecl):

class FunctionDecl : public ValueDecl, public DeclContext {
....

ScopedDecl would have a DeclContext member and 
isDefinedOutsideFunctionOrMethod would check if it's a FunctionDecl.
