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.

Dollar quoting was specifically invented so that people would not have
to use torrents of backslashes and/or single quotes.
