Describe the bug

This is hard to explain, so please consult the examples below.

How to reproduce

〉[1 2 3] | do { print $in } | print 'Done'
╭───┬───╮
│ 0 │ 1 │
│ 1 │ 2 │
│ 2 │ 3 │
╰───┴───╯
Done
〉[1 2 3] | each { print $in } | print 'Done'
Done
〉[1 2 3] | for i in $in { print $i } | print 'Done'
Done
〉[1 2 3] | each { print $in }
1
2
3
〉[1 2 3] | each { print $in } | 25
25

As you can see the print $in commands (EDIT: I mean 2nd, 5th and 3rd examples) don't work because the pipeline of the each or for pipes the block's result into print 'Done' or 25. do does not seem to have this problem, however. Thus, I suspect the issue lies with how the loops iterate over single values of the input list.

Expected behavior

I expect the print statements to work correctly.

And when :

> [1 2 3] | do { each { print $in } } | print 'Done'
Done

Interesting

I expect the print statements to work correctly.

I'm not sure which is "correctly" from your perspective. Do you mean this?

〉[1 2 3] | do { print $in } | print 'Done'
╭───┬───╮
│ 0 │ 1 │
│ 1 │ 2 │
│ 2 │ 3 │
╰───┴───╯

Do you mean this?

〉[1 2 3] | each { print $in }
1
2
3

Are both of those correct? or wrong? or is "correct" different for each case? or does is the first one right if it prints 'Done'?

Sorry, I misworded that message. I meant all of these:

〉[1 2 3] | each { print $in } | print 'Done'
Done
〉[1 2 3] | for i in $in { print $i } | print 'Done'
Done
〉[1 2 3] | each { print $in } | 25
25
