091 template variant interpolation

// Test: `|template(once)|zig` actually performs Liquid interpolation. The body
// references `{{ proc_name }}` which the template processor substitutes
// with the proc's path before stripping `template` and emitting Zig.
//
// The rendered proc body prints the literal "ping" — which is the
// proc's name, supplied through the template context.

~import "$std/io"

const std = @import("std");

~pub event ping {}

~proc ping|template(once)|zig {
    std.debug.print("proc was: {{ proc_name }}\n", .{});
}
