<p class="MsoNormal">The RecursiveASTVisitor does not appear to support visiting const-qualified statements since its VisitStmt member function accepts a pointer to an unqualified Stmt:<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">By contrast, the ast_matcher’s getNodeAs function returns a pointer to a const-qualified node type:<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I was using the ast_matcher but reached a point where I needed to apply a RecursiveASTVisitor to the result of a getNodeAs call to check for something deeply nested (without writing more matchers to get me through any possible thing I might
encounter on the way down). Unfortunately, it looks like I can’t do that without resorting to an ugly const_cast and assuming that the visitor does not actually modify any Stmts.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Am I missing something? Is there a const-alternative to RecursiveASTVisitor?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
