pub struct Push;

Function that appends a value onto a tuple.

Type

fn<T>([T], T) -> [T]

Examples

let program = r#"
    repeat = |x, times| {
        (_, acc) = (0, ()).while(
            |(i, _)| i < times,
            |(i, acc)| (i + 1, push(acc, x)),
        );
        acc
    };
    repeat(-2, 3) == (-2, -2, -2) &&
        repeat((7,), 4) == ((7,), (7,), (7,), (7,))
"#;
let program = Untyped::<F32Grammar>::parse_statements(program)?;
