I am trying to run tests on linux, win and mac. I would like that to test both stable and nightly on each of those. The trouble starts when I take this configuration and modify the rust: nightly entry at the top to include both nightly and stable.
I was expecting it to run the matrix and run each of those on both versions of rustc, but instead I get:
- linux: nightly + 2 times stable
- windows and mac: just stable.
Is there a way to make this work without having to duplicate all the instructions in each matrix variant for both rustc versions?
