Did just a first test. The RTree test.nim from [https://github.com/StefanSalewski/RTree/tree/master/tests](https://github.com/StefanSalewski/RTree/tree/master/tests) compiles but running the executable gives an assertion error. Funny.
Unfortunately gintro apps seems not to compile, seems that finalizers are not supported. I expected that gintro would not work with newruntime because GC_ref was not available, but had some hope for ARC. But without finalizers support -- again no idea what I could do.
