Describe the bug

I can write a try/catch which reports whatever error from the try block, or I can catch that error in the catch block and do some cleanup. But I can't do both in the same script.

I want to be able to do both of these in unit tests for (standard) library script modules. e.g, some tests create temporary files and I want to clean those up whether the tests succeed or fail. And I would also, very much, like to see an error if a test fails.

How to reproduce

Report the specific error that occurs in a try closure:

let t = try {
    echo "1: top of try closure"
    1 / 0
    30
} catch {  | error |
    #echo $"2: in catch closure, returning 42"
    echo $"3: in catch closure, error is ($error | debug) returning 42"
    42
}

echo $"4: after try/catch, t is ($t | debug)"
echo ""

Produces:

〉nu trycatch.nu
1: top of try closure
Error: nu::shell::division_by_zero

  × Division by zero.
   ╭─[/home/bobhy/work/nushell/trycatch.nu:2:1]
 2 │     echo "1: top of try closure"
 3 │     1 / 0
   ·       ┬
   ·       ╰── division by zero
 4 │     30
   ╰────

Note that messages 2 and 4 are MIA.

Catch the error and clean up after it:

let t = try {
    echo "1: top of try closure"
    1 / 0
    30
} catch {  | error |
    echo $"2: in catch closure, returning 42"
    #echo $"3: in catch closure, error is ($error | debug) returning 42"
    42
}

echo $"4: after try/catch, t is ($t | debug)"
echo ""

Produces:

〉nu trycatch.nu
1: top of try closure
2: in catch closure, returning 42
4: after try/catch, t is 42

Here, messages 2 and 4 both appear. I could put cleanup code in either place.

Expected behavior

I was hoping the error from the try closure would be passed into the catch closure as the closure argument (or perhaps in $in). From reading the code, it appears to be at least trying to do both of these things, but I doesn't seem fully functional, or I'm misunderstanding something (very likely).
