Personally, I don't care about executable size much, but I find creating
custom source file and linking it into executable a very indirect method.
It is hard to implement from IDE side, too, because IDE can be used to
debug projects that are build by JRHackerBuildSystem, and be unable to
automatically add source files to build. My ultimate goal is allowing IDE
user to just specify 10 pretty-printer packages, and have them work on
every single project he's working on.
