edition = "2026"

[build]
target = "rust"
runtime = "tokio"
error_model = "enum"
EOF

cat > src/main.crp <<'EOF'
shape Named = {
    name: str
}

type Guest = {
    name: str = "world"
}

id(x: T) = x

greet(who: Named) = "hello {who.name}"

pub main() = {
    world := Guest {}
    print(id(greet(world)))
}
EOF

crisp run .
