New Feature 🔥

Is your feature request related to a problem? Please describe. 🤔
I've noticed that some of my code operating on the children of a TagRef' is now broken. Basically this seems to be because the children now appear as seq[Node] instead of seq[TagRef] when passed around as data.

Describe the solution you'd like 💡
Since making a TagRef through buildHtml only to take out a seq of children TagRefs is a bit convoluted, I thought it might would be a good time to implement some templates for creating seqs of to-be-rendered DSL data. I'd use something like this myself in my own development system if it wasn't integrated into happyx. Note that currently the TagRef based approach of buildHtmls fails and only the thunk based approach works in a straightforward way.

template thunkHtml(body: untyped): proc(): TagRef =
  proc(): TagRef = buildHtml:
    body

template thunkHtmls(body: untyped): seq[proc(): TagRef] =
  block:
    var res: seq[proc(): TagRef]
    template html(b: untyped) =
      res.add:
        proc(): TagRef = buildHtml:
          b
    body
    res

template buildHtmls(body: untyped): seq[TagRef] =
  block:
    var res: seq[TagRef]
    template html(b: untyped) =
      res.add:
        buildHtml:
          b
    body
    res

let htmlProcs = thunkHtmls:
  html:
    tSpan: "front"
  html:
    tSpan: "back"

let htmlTags = buildHtmls:
  html:
    tSpan: "right"
  html:
    tSpan: "left"

component FormatProcHtml:
  p: (proc (): TagRef) # parentheses needed in avoid "nested statements" error
  html:
    em(style="color:blue"): {self.p()}

component FormatTagHtml:
  t: TagRef
  html:
    em(style="color:blue"):
      {self.t.val}

appRoutes("ROOT"):
  "/":
    for i in 1..5:
      tDiv:{$htmlProcs[0]()}
      FormatProcHtml(htmlProcs[1])
    for i in 1..5:
      tDiv:{$htmlTags[0]}
      FormatTagHtml(htmlTags[1])

Solved in the next commit, thx
