@wingo and there's no /bin/env to get it confused with

this lets you use guix shell as a shebang line, e.g. #!/usr/bin/env -S guix shell python -- python3

@wingo Interesting it isn’t in posix: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/env.html

Seems like it should get added, I can’t thing of a reasonable workaround.

@leonidas @wingo The #! parsing happens within the kernel. If you start splitting arguments on spaces, which other shell features should the kernel implement? Quoting? Backslash escapes? Environment variable expansion?
