Steps to reproduce

Try to use a symbol for true-value for a checkbox input.

What is expected?

That it works and that v-model gets the symbol value when checkbox is checked.

What is actually happening?

Browser complains that it cannot convert Symbol to a string: Cannot convert a Symbol value to a string.

To explain the use case here: I have some user supplied values (strings) I use for checkbox values, but I also want to include checkboxes for special system values (like "all", "none", etc.). So that there is no overlap/conflict between strings, I wanted to use Symbols for system values. I could find some other way escape those strings (like a prefix), but Symbols look to me like the perfect solution available in the language for this.

[dadaguai-git]

In the compilation process of Vue, Symbol cannot be used as a value. During the compiler's operation, event names, directives, etc., are converted into string form.However, Symbol cannot be converted into a string type.
If the explanation is incorrect, please forgive me.

If the explanation is incorrect, please forgive me.

It's incorrect, unfortunately.

[dadaguai-git]

It's incorrect, unfortunately.

I apologize. If possible, could you also share the reason why Symbol cannot be used? I would like to learn more about it.
