I implemented some generic logging module and want to use

mixin template makeLogger( params,,, name ) {
Logger logger;
static this () {
.. logger initialization...
}
}
-------------
module another;
import log;
mixin makeLogger!( ...., __MODULE__ );
logger( DEBUG, "aksjfakjdf" );
-------------
module yet_another;
import log;
mixin makeLogger!( ...., __MODULE__ );
logger( INFO, "sdfsdfsdf" );
This works quite well, but if I import one module into another
I get an
obvious name clash on the variable name "logger". I have many
modules where
I want to use logging, so things like static import are not an
option.
Is there any pattern I could use here?
is it necessary use multiple loggers? maybe you should move ur
Logger instance to module scope(log module) and just handle log
sources some other way(i.e. add source string mapping in log
module)? because i mean this clash is just due to multiple
instantions of this template
