The string BODY in $BODY$ has no syntactical significance. You could just as easily use $$ or $supercalifragilisticexpialidocious$. The only place where the string inside matters is when you're nesting dollar quoted structures. > Also why in the single-quote syntax, each backslash will be written > as four backslashes? While this will not be needed in the > dolar-quoted string? Dollar quoting was specifically invented so that people would not have to use torrents of backslashes and/or single quotes.
