The problem with that is the presence of an existing prefix:<|> operator. One could fake it with a postfix:<|> macro that rewrites the AST produces by the prefix, except no one implements macros yet. But circumfix openers have to share longest-token space with prefixes. You could maybe use broken bar instead, circumfix:<¦ ¦>. Larry
