Keep in mind that the goal of this self-answered question was not to make module recommendations. Rather, it was to explain what the "big picture" differences are, between the modules, etc. (more) |

I'll add this last comment to note that the suggestion in this post skips the composite nodes and adds only the leaves, which deviates from the desired behavior mentioned in the OP. (See footnote #2.) (more) |

A: Recursive traversal of composite tree of mutable "trait objects"? Here's the solution I ended up with a while back to traverse the (sub-)tree, starting at the given root component. In short, the model's field, `components`, is used directly and small `unsafe` blocks are used to push the root's children into the vector-backed queue that's currently being traversed. ... (more) |

> It doesn't really assume anything, it just asks why someone would consider it dangerous
It does make assumptions. Asking "Why is [it] dangerous?" is not the same as asking "Is [it] dangerous?". (more) |

The question just assumes the `auto` keyword is "dangerous". Are there examples that are "dangerous" that can be added into the OP? Is it simply surprising/unexpected behavior? Perhaps it'd be more useful to ask what the committee's *intent* is and the problem they're trying to solve with it? (more) |

Recursive traversal of composite tree of mutable "trait objects"? I'm working on a background service/daemon for an embedded device, in Rust. The daemon manages several hardware components and these are structured using the Composite design pattern. The composite type from the pattern is called `Component` in the service: ```rust pub trait Component: // ..... (more) |

> Re: big targets: Hmmm, I would reconsider that after the xz backdoor.
Well, given that xz is/was(?) a widely-used piece of software, yes, they had a significant amount of attack surface area (i.e. thousands, even millions, of users). That's a big target. You as an individual? Not so much. (more) |

@#63752 I think using `open` makes more sense b/c it implicitly checks for your ability to read the file, which is necessary for the program to work correctly, among other things.
For example, in GNU+Linux, you could remove all permissions from the wallpaper file, including read, and `os.path.exis... (more) |

I'd suggest that you overload the `<<` operator instead of having a `print` method. That way, you should be able to take your `Car c;` and write `std::cout << c << std::endl;`, and so on. This is what the `std::string` class does. (more) |

After looking around the registry with the Registry Editor, I couldn't find anything else that seemed to indicate the *current* path to the current wallpaper or anything. So, it's very possible for the user to set an image as a wallpaper and then (re)move it, causing the Windows registry entry to end... (more) |

@#53177 It would be and that's what I was doing earlier today. Unfortunately, what I found is potentially unreliable. On Win7, had to use Python 3.7 (latest release that will work there). This code seems to work:

@#53177 No harm no foul. The way I got it to work from Python in Windows 10 was as follows (had to use a list for the commands, unlike in GNU+Linux):
```python
command = [

'Get-ItemPropertyValue',
'-Path',

I found a way to make it work in Python3 (in Windows 10). I'll be updating the post later. Also, while PowerShell *is* installed in Windows 7, the `Get-ItemPropertyValue` command returns an error message, suggesting the command is not implemented. (more) |

@#53177 Your method shows error messages when attempted via Python3's `subprocess` module.
