What is Fish equivalent for <<EOF in Bash

Question

What is the Fish equivalent for << in Bash, as in

$ nc localhost 8888 << EOF
> foo
> EOF

In Fish, it crashes

> nc localhost 8888 << EOF
fish: Expected redirection specification, got token of type 'Redirect input to file'
nc localhost 8888 << EOF
               ^

Answer 1

Thanks to the link provided by Etan I found out that such feature is not implemented, and the closest thing available is

> echo "\
  foo
  " | nc localhost 8888

Answer 2

That is not implemented in Fish. You can read about Bash/Fish syntax crossovers HERE.
