-## Why do I have to cast std::nullopt to a specific optional type when calling a templated function i.e.
-
-```c++
-template<typename T>
-void DoSomething(std::optional<T> = std::nullopt, bool report_errors = false);
-```
-
-```text
-DoSomething() works fine.
-DoSomething(std::nullopt, true) no matching function for call to 'DoSomething' Do_Something<std::optional<string>, bool>(
-```

 ## Which is uglier
 ```c++
 (*after_each)()
 after_each->operator()()
 after_each.value()();
 ```
