Thanks @martong Yes, I tried another matcher with typedefNameDecl which also
did not match:
match callExpr(allOf (callee(functionDecl(hasName("std::sort"))),
hasArgument(0,
stmt(hasDescendant(expr(hasType(typedefType(hasDeclaration(typedefNameDecl(hasName("value_type")))))))))))

How then do you think I should try matching the IntPointerArray example? I am
now leaning towards not doing this via AST Matchers as I am not sure if I can
easily match more complex cases.
