That failing code isn't valid fish script - it's for bash's completion
framework, which is wholly incompatible. So the "source" mode here doesn't
work for fish.
What exactly is the issue with the "source-fish" mode? Can you post the
output of `env _MOLECULE_COMPLETE=source-fish molecule`?
Also, `eval` here adds a bit of overhead. If you don't need the command to
have access to stdin, you can just pipe to `source` - `env
_MOLECULE_COMPLETE=source-fish molecule | source`.
