Named template holes, positional rendering, and forma capture.

# =============================================================================
# named-holes — Named template holes and erased positional rendering.
# =============================================================================
#
# What this teaches:
#   • named-only template application: "§{greet} world"(greet: "Salve")
#   • mixed named and anonymous STRING holes with positional actuals
#   • forma capture with a labeled actual; the captured template is erased to §
#   • named holes erase before rendering, so the output is ordinary text
#
# Reject teaching rows (comments only; these must not become stage-3 inputs):
#   • ordinary-call label: f(greet: "x")
#   • `=` form: "§ world"(greet = "x")
#   • unknown label: "§{greet} world"(other: "x")
#
# See also: forma, scriptum, string, textus, §
# =============================================================================

main {
    # A labeled actual fills the named hole.
    const _ named ← "§{greet} world"(greet: "Salve")
    print named

    # A named and an anonymous hole share one positional sequence.
    const _ mixed ← "§{greet} §"("Salve", "Mundus")
    print mixed

    # Named-hole erasure renders the same as the positional § form.
    const _ erased ← "§{greet} world"("Salve")
    print erased

    # Forma capture accepts labels but stores only erased template text.
    const _ captured ← `where id = §{id}`(id: "42")
    print captured.template
}

Expected output:

Salve world
Salve Mundus
Salve world
where id = §
