subflow immediate

// ============================================================================
// VERIFIED REGRESSION TEST - DO NOT MODIFY WITHOUT DISCUSSION
// ============================================================================
// Test: Immediate subflow with field mapping
// Feature: ~event_name = branch { output-field: input_field }
// Verifies: Input fields are accessible and mapped to output correctly
// ============================================================================

import std/io

// Event: takes a name, produces a greeting message
tor greet { name: string } -> string

// Subflow implementation: maps input directly to output
greet -> name

// Test: call greet with "World" and print the resulting message
greet(name: "World"): g |> std/io:print(g)
