Error: `expected parenthesis in `#[parse_terminated(...)]``

[bravely-beep]

The docs say #[parse_terminated] takes no arguments, but attempting to use it gives the error:

expected parenthesis in `#[parse_terminated(...)]`

Example:

mod kw {
    syn::custom_keyword!(nop);
}

#[derive(Parse)]
pub struct Program {
    #[parse_terminated]
    instructions: Punctuated<Instruction, Token![,]>,
}

#[derive(Parse)]
pub enum Instruction {
    #[peek(kw::nop, name = "nop")]
    Nop,
}

I'm also getting this error under the same circumstances.

A temporary workaround is using #[call(Punctuated::parse_terminated)], which seems to work as well.
