Passing This code compiles and runs correctly.
Code
// Test: ~if uses REAL template system (lookupTemplate + interpolate)
//
// This test verifies that the ~if transform:
// 1. Calls template_utils.lookupTemplate(program, "if")
// 2. Finds the template defined in control.kz
// 3. Interpolates with ${condition}, ${| then |}, ${| else |}
// 4. Uses the result as inline_body
//
// This is ACTUAL template metaprogramming, not hardcoded string building!
// Mom can put this on the refrigerator.
~import std/io
const std = @import("std");
const value = 42;
~if(value > 10)
| then |> std/io:print("Template says: greater!\n")
| else |> std/io:print("Template says: not greater!\n")
Actual
Template says: greater!
Expected output
Template says: greater!

# The template produces: if (${condition}) { ${| then |} } else { ${| else |} }
# The branch bodies are comptime print transforms — they land as inline
# debug.print calls inside the if/else (print is a transform, not a runtime
# handler, since 2026-06-11).
