How to define an alias in fish shell?

Question

I would like to define some aliases in fish. Apparently it should be possible to define them in

For posterity, fish aliases are just functions:

$ alias foo="echo bar"
$ type foo
foo is a function with definition
function foo
    echo bar $argv; 
end

To remove it

$ unalias foo
/usr/bin/unalias: line 2: unalias: foo: not found
$ functions -e foo
$ type foo
type: Could not find “foo”
