terminal: smart send not working when returning dict

[hutch3232]

Type: Bug

Behaviour

Function definitions that return a list or dict directly don't fully send to terminal unless it's surrounded by parentheses.

Steps to reproduce:

Start with this script:

def foo():
    return {
        "a": 1
    }


def bar():
    return {"a": 1}

# this line works on python <= 3.12.8
# BUT throws an indentation error on python 3.13.1
def baz():
    d = {"a": 1}
    return d


def bar2():
    return ({"a": 1})

Ensure Smart Send is on and that Native REPL is OFF. Then use shift+enter to try and run each function definition.
