✨ Implement a `fragment` to contain multiple elements at once

[hayleigh-dot-dev]

In other frameworks it's often quite handy to be able to return multiple elements without wrapping them in some single container. Lustre should support this too! We should define a new variant of the Element type...

  pub opaque type Element(msg) {
    ...
+   Fragment(List(Element(msg))
    ...
  }

... as well as exposing a new constructor for it.

pub fn fragment(children: List(Element(msg)) -> Element(msg) {
  Fragment(children)
}

Then the render methods to_string and to_string_builder as well as the runtime need to be updated to support this new element type.

If this is still up for grabs, I'd love to try implementing it!

Cool package! Curious if help is still wanted on this? I think there was some drift in the current implementation vs what's there today but I think I have enough understanding to put this together

[hayleigh-dot-dev]

If you think you could work it out I'd be very grateful! It has so-far eluded me, I'd appreciate someone that knows what they're doing chiming in 😅

[JScearcy]

Awesome, thanks! I'll post an initial approach this afternoon for consideration

[JScearcy]

I posted an initial draft PR, if anyone has feedback or suggestions I'm happy to update, after an initial round I can work on a more complete integration. Initially I just focused on the client runtime

Edit: Gonna resolve the conflicts , still open for feedback in the mean time but def gotta weave things together
