010 plain value branch

// Test plain value branch return in subflows
// Syntax: ~event = branch { expr } instead of branch { field: expr }

const std = @import("std");

// Event with plain value branch (not a struct)
~event double { n: i32 }
| result i32

// Subflow with plain value return - no field name needed!
~double => result { n * 2 }

// Another example with expressions
~event square { n: i32 }
| result i32

~square => result { n * n }

// Printer event
~event print-results { a: i32, b: i32 }

~proc print-results|zig {
    std.debug.print("{} {}\n", .{ a, b });
}

// Main flow - chain subflows
~double(n: 5)
| result a |> square(n: 4)
    | result b |> print-results(a, b)
