Just for completeness, the tie does not need to become manifest
as a component. It could be a call, or it could be a message sent
when the Logger_State object is initialized, or finalized.

When the program becomes multithreaded, a question will be whether
multiple loggers should write to multiple files, too. If they should
write to the same file, then this requirement together with a File_Type
component mean that proper serialization of calls needs to be added
to Logger_State in addition.
