I was going to say it doesn't need them, since it doesn't accept any
arguments, but then I saw that we already use those empty parens
everywhere.

So, reluctantly, OK for the parens.

>  @defvar Breakpoint.enabled
>  This attribute is @code{True} if the breakpoint is enabled, and
> -@code{False} otherwise.  This attribute is writable.
> +@code{False} otherwise.  You can use it to enable or disable the breakpoint.
> +This attribute is writable.
>  @end defvar

The order is wrong: first say that it's writable, then that it can be
used to enable/disable.

OK with that change.

Thanks.
