[cfe-dev] Could I get the Parent AST of a Stmt？

[Kirill Bobyrev via cfe-dev]

As far as I understand the issue:

1. You might want to pass **string* to the *ASTContext::getParents()* 
function as it doesn't accept pointer to the AST node of any kind.
2. *ASTContext::getParents()* returns *DynTypedNodeList* and it can't be 
implicitly converted into a *ParentVector*.

Hope that helps,
Kirill Bobyrev
