Since the VDOM API supports it, I don't see why the macro shouldn't. Thanks for the PR!

GH actions should not have approved this

[cecton]

I'm not sure why/how a byte would be useful? A byte is literally a u8, so it's converting b'a' to the string "97"?

[its-the-shrimp]

It would indeed be strange to use a byte literal in HTML, but who knows what use cases are there in the wild, I think it would be even more strange to pretend like it's not stringifiable at compile-time.

[ranile]

That is a valid point. What if we improved the diagnostic instead of just saying "invalid type"?

[its-the-shrimp]

What if we improved the diagnostic instead of just saying "invalid type"?

I did just that for byte-string literals in this PR, the only Rust literal kind that generates a non-Displayable value.

[futursolo]

This is similar to ByteStr, however since a byte is u8 and u8 supports Display.
So I am not sure not allowing b'A' would be effective.

[futursolo]

Thanks! LGTM.

I'm sorry it took me this long to merge this
