clang-query> m classTemplateSpecializationDecl(<tab>
clang-query: /usr/local/google/home/klimek/src/llvm/tools/clang/include/clang/ASTMatchers/Dynamic/VariantValue.h:51: ast_type_traits::ASTNodeKind clang::ast_matchers::dynamic::ArgKind::getMatcherKind() const: Assertion `K == AK_Matcher' failed.
Comment 1 Samuel Benzaquen 2014-10-09 09:45:15 PDT 
The overloads for isSameOrDerivedFrom break the assumption at Registry.cpp:441:
---
// This currently assumes that a matcher may not overload a
// non-matcher, and all non-matcher overloads have identical
// arguments.
---

isSameOrDerivedFrom() has an overload for Matcher<NamedDecl> and for StringRef.
