Version comparisons are very well defined; but I guess you're referring to MELPA's horribly-broken approach to versions here? A test with a package installed from MELPA confirms that `package-desc-version' and `package-get-version' do pick up on whatever version MELPA assigned, so I guess that's unreliable as you say. Along with my earlier misgivings about assuming that any given library had been installed as a package in the first place, I agree that this doesn't seem like a viable approach. The code itself would include the *real* version number, though, so in principle I think it would be possible to utilise that; but I think it's currently only exposed in the .el source. If the .elc file contained the version number as well, I think that load-time version-update tracking would become possible? -Phil
