    For example:
```
template<typename T>
class A{
public:
    T t;
    A(T t) : t(t) {}
};

template<typename T>
auto foo(T t) {
    return [tt = t](){return tt;};
}

int bar(int a, int b, int c) {
    auto lambda1 = [](int a, int b) {
        return a + b;
    };

    auto lambda2 = [&]() {
        return a + b + c;
    };

    A<decltype(foo(lambda1))> a1(foo(lambda1));
    A<decltype(foo(lambda2))> a2(foo(lambda2));
 return a1.t()(a, b) + a2.t()();
}

int main() {
    return bar(1, 2, 3);
}
```
When I dump the qualified name by `QualifiedName(clang::TypeName::getFullyQualifiedName(ctx_->getRecordType(decl), *ctx_, ctx_->getPrintingPolicy(), true))`, there are two same qualified name:
```
::A<(lambda at test3.cpp:10:12)>
::A<(lambda at test3.cpp:10:12)>
```
correspond to:
```
A<decltype(foo(lambda1))> a1(foo(lambda1));
A<decltype(foo(lambda2))> a2(foo(lambda2));
```
How can I dump more information about lambda1 and lambda2? I initially want to use `QualifiedName` to represent one struct type until I met this situation.
