It seems that #41 fixes that, whenever that gets merged.

It seems that #41 fixes that, whenever that gets merged.

CIL is no longer being actively maintained (see e.g. the discussion in this PR: #42), so that PR likely won't be merged ever. There's several forks that see some active development --- these are your best bet if you run into further issues with the original CIL.

If someone wants to start maintaining this, I'm sure that could be arranged for.
