Unfortunately this gives again the private ctor error (the same error when I
called explicitly the overload with the `DeclarationMatcher`):
../../git/llvm/tools/clang/include/clang/ASTMatchers/ASTMatchersInternal.h:1339:13:
error: calling a private constructor of class

Even if it would work then how could I support nodes other than decls (e.g.
stmt())?
