static nested scope
     
         Where the {scope} of an {identifier} is fixed at
        {compile-time} to be the smallest {block} ({begin}/end,
        {function}, or {procedure} body) containing the identifier's
        {declaration}.  This means that an identifier declared in some
        block is only accessible within that block and from procedures
        declared within it.
     
        This term is used in the {Python} community.
     
        Compare {lexical scope}.
