Struct NestedBlock 

pub struct NestedBlock<'a> {
    pub members: &'a [NestedDecl],
    pub num_params: usize,
    pub levels: &'a [String],
}

A block of source families, each nesting itself or a sibling inside registered containers: one family, or an ordinary mutual block. The members share num_params uniform parameters and the universe parameters levels, and may each carry indices of their own.
