  <template name="_with-static-reachable_">
    All expressions here are reachable
      (having been derived from named statements).

    <rate yields="tplStaticA">

  <template name="_with-static-unreachable_">
    This expression is on its own unreachable,
      intended to be expanded into another expression.

    <c:sum>
      <c:product />
    </c:sum>

    <c:product>
      <c:sum />
    </c:product>
  </template>

  <template name="_with-static-mix-reachability_">
    Both reachable and unreachable,
      with the intent of expanding into an expression but also providing
      itself with supporting expressions.

    <c:sum>
      <c:product />
    </c:sum>

    <c:product> <!-- depth N -->
      <c:sum /> <!-- depth N+1 -->
    </c:product>

    The above expression will end at depth N+1,
      to be auto-closed.
    The below expression will yield an Ident->Expr,
      and so will _begin_ at N+1.
    We must therefore ensure,
      and this test do so assert,
      that this matching depth does not cause the reparenting of this next
        expression into its preceding sibling.

    <rate yields="tplStaticMix" /> <!-- begins at depth N+1 -->

    <c:sum>

  Short-hand template application.
  These get expanding into the long form so that we don't have to translate
    back and forth between the underscore-padded strings.
  The fixpoint test will further verify that TAMER also recognizes the long
    `apply-template` form,
      asserting their equivalency.

  Shorthand template bodies desugar into the param `@values@`.
  Unlike in the XSLT-based TAMER,
    metavaraibles (template parameters) are purely lexical,
    and do not contain trees,
    simplifying its implementation.
  Desugaring instead takes advantage of existing features by generating a
    _new_ closed template with the body from the shorthand application.
  Since closed templates can be applied by referencing them as a value,
    which expands them in place,
    this ends up having the same effect as a `param-copy`.

  For now,
    the expected output asserts on this behavior,
    but if this has a significantly negative impact on performance of the
      XSLT-based compiler,
        then it'll have to inline during desugaring.

  This asserts verbatim on the output,
    which uses a generated id based on the span.
  This is fragile,
    and it may break often;
      just take the hex span from the test failure in that case.
