It's better to write functions than use "alias". "alias" is a sort of
a crutch; in Fish, it's a function that creates a simple function for
you, but functions in general are more powerful than "aliases".

Do these problems occur on Linux or only on MacOS? type, which and
alias work on my standard install of Fish 1.23.1 on Linux:

type is a builtin

vi is /usr/bin/vi

which is /usr/bin/which
~> type alias
alias is a function with definition
[...]

/usr/bin/vi
~> alias vi=vim
~> type vi
vi is a function with definition
function vi
vim $argv
end
~> alias hello vi
~> type hello
hello is a function with definition
function hello
vi $argv
end

Feel free to extend the "alias" function with these features:
1. Handling the case when there are no arguments
2. Querying for an alias. You could simply call the "functions" builtin here.
