While fiddling with the LLVM demangler, I noticed that in the following example
```
template <typename T>
struct Bar{};
template <typename K>
struct Foo {
template <typename T, template<typename U> typename S>
void method(S<T> t, S<K> k);
};
void s() {
Foo<int> k;
Bar<int> i;
Bar<bool> b;
k.method(b, i);
}
```
the call `k.method(b, i)` is mangled as `_ZN3FooIiE6methodIb3BarEEvT0_IT_ES3_IiE`, which appears right (`Foo<int>::method<bool, Bar>(Bar<bool>, Bar<int>)`).
However, running the demangler
```
llvm-cxxfilt -n _ZN3FooIiE6methodIb3BarEEvT0_IT_ES3_IiE
```
produces `void Foo<int>::method<bool, Bar>(Bar<bool>, bool<int>)`.
`bool<int>` is obviously wrong and seems to stem from the `S3_` substitution.
