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.

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.
