New comment by mhmdanas on void-packages repository https://github.com/void-linux/void-packages/pull/36121#issuecomment-1067409478 Comment: The error only occurs because Fish 3.4.0 introduces a new syntax that the script in question was modified to use in Fish 3.4.0, and older Fish versions don't recognize that syntax. Thus, any Fish sessions started after the update will not be affected. I think applying such a patch is not a good idea, but I'll leave that choice to the maintainers.
