If you have a template in an anonymous namespace we will warn about it being unused even if it is referenced by another template, *if* the other template is not instantiated.
i.e compiling the following with -Wunused-template
```cpp
namespace {
template <class T> void foo(T*){}
}
template <class T> void bar(T* t) {
foo(t);
}
```
produces
`warning: unused function template 'foo' [-Wunused-template]`
The only way to silence this is by using a `[[maybe_unused]]`, which is a solution but is somewhat suboptimal.
