I'm eager to try out `--gc:arc` in a project and tried compiling [Rosencrantz](https://github.com/andreaferretti/rosencrantz) using it and I'm getting: $ nimble server Executing task server in /home/boisvert/git/rosencrantz/rosencrantz.nimble Verifying dependencies for [email protected] Compiling tests/server (from package rosencrantz) using c backend /home/boisvert/.choosenim/toolchains/nim-#devel/lib/system/threads.nim(104, 28) template/generic instantiation of `add` from here /home/boisvert/.choosenim/toolchains/nim-#devel/lib/system/seqs_v2.nim(111, 21) Error: system module needs: nimDestroyAndDispose Tip: 1 messages have been suppressed, use --verbose to show them.

"--hints:off" "--forceBuild" "--out:tests/rosencrantz" "--linetrace:on" "--linedir:on" "--debuginfo" "--stacktrace:on" "tests/server" Run
(I changed the local nim.cfg to `--threads:on --gc:arc`) What does this `Error: system module needs: nimDestroyAndDispose` error mean? Is it a compiler issue or a code-to-be-compiled issue? thanks! PS: I'm using the latest `devel` branch installed with `choosenim`
