Not as far as I know. You can use the "and" built-in inside the script:
#!env fish
echo blah
and false
and echo 'This will never get executed'
Or maybe you can write a function that does that. Something like:
function and_all
for x in $argv
if not $x ^/dev/null
return $status
end
end
end
Then the script could use it like:
#!env fish
and_all \
false \
echo 'This will never get executed'
It's a bit ugly and slow, but it's more explicit than in Posix.
