    A good time to refresh my Rust folder as a whole to see what features got stabilized, removed, or subsumed.

    My current list of used unstable features is down to 20.
    Some lang, some lib.
    A couple incomplete.
    Some are more important than others.

    #![feature(adt_const_params)]
    #![feature(async_closure)]
    #![feature(const_type_name)]
    #![feature(duration_constants)]
    #![feature(extract_if)]
    #![feature(generic_arg_infer)]
    #![feature(impl_trait_in_assoc_type)]
    #![feature(iter_array_chunks)]
    #![feature(let_chains)]
    #![feature(macro_metavar_expr)]
    #![feature(map_try_insert)]
    #![feature(never_type)]
    #![feature(once_cell_try)]
    #![feature(proc_macro_hygiene)]
    #![feature(specialization)]
    #![feature(step_trait)]
    #![feature(stmt_expr_attributes)]
    #![feature(try_blocks)]
    #![feature(try_find)]
    #![feature(type_changing_struct_update)]
