Here is my implementation of SmartPointer. It is intrusive and tiny. How can I improve it? For example, constexpr, nonexcept, try-catch-throw, and etc.

Imagine code that reads from a file, cleans the data and finally writes the cleaned data to a new file.
Let's briefly define these methods as Ruby stubs:

end
def read

end
We can also have an orchestrator method that triggers the whole logic:
