Well phobos as a library is precompiled, so the versions used

For templated functions version identifier will "leak" from

could you elaborate please? Currently I use the version
statements in two template functions. I'm not sure why one would
brand this negatively as a leak into the library.
Also the version identifiers of client code determine which
declarations you see.
Relying on this would be a constant source of bugs.

I did proof-of-concept yesterday using type tags and template
constraints to statically disable certain log levels.
It also has some drawbacks because LogLevel is no longer a
plain enum, but it's more appropriate than version identifiers.

Thank you for taking the time, but I found several conceptional
problems with that POC. The worst being that if I make the
LogLevel inside the TestLogger anything other than a enum it
fails, as it is used in the template constraint. That would mean
the LogLevel is fixed at CT.
