could you elaborate please? Currently I use the version

For example we don't reinstatiate templates if they are
instantiated in an imported module. But that module might have
been compiled with different settings.
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.
Well if your test logger only knows it's log level at runtime,
then you obviously can do the comparison only at runtime. You can
solve this by checking whether minLogLevel is a compile time
constant in the log constraints adding another overload for
runtime configurable log levels.
