[https://github.com/StefanSalewski/gintro/issues/66](https://github.com/StefanSalewski/gintro/issues/66) it seems that your when defined(gcDestructors): is the more correct test, as when compileOption("gc", "arc") seems not to compile at all for old stable Nim. I think I will replace that, but maybe wait for Araq for confirmation, as I will not waste to much release numbers. 0.7.1 is already close to 0.9.9 unfortunately.
