I'm not sure it works like that now. This seems to work fine.

def greet [name] {
  ["hello" $name]
}

❯ greet moon
╭───┬───────╮
│ 0 │ hello │
│ 1 │ moon  │
╰───┴───────╯

However, this is really how I think it's meant to work currently.

def greet2 [name] {
  ["hello" $name]
  $name
}

❯ greet2 moon
moon

You'll notice that ["hello" $name] doesn't print out in greet2. This is because we only return/print the last item.

But if you try greet3, you'll see that both print again.

def greet3 [name] {
  echo ["hello" $name]
  echo $name
}

❯ greet2 moon
╭───┬───────╮
│ 0 │ hello │
│ 1 │ moon  │
╰───┴───────╯

moon

Ah I see

When I initially started out writing functions I called them multiple times in a script and was confused as to why I only got the output of the last function call

def greet [name] {
  ["hello" $name]
}

greet "one"
greet "two"

only outputs

╭───┬───────╮
│ 0 │ hello │
│ 1 │ two   │
╰───┴───────╯

without the explicit print

It wasn't until I found that comment I linked to, that it made sense.

I can close this if it's not relevant to have the explicit print, but personally I think it would help some newcomers as I ran head first into this 😄

It literally just struck me that it's an implicit return 🤦 now I understand. Started learning Nu yesterday haha
