hi Velocity team:

2) Advanced Issues: Escaping and !
      #set( $foo = "bar" )
      $\!foo
      $\!{foo}
      $\\!foo
      $\\\!foo

    This renders as:
      $!foo
      $!{foo}
      $\!foo
      $\\!foo

   My output is:
      $!foo
      $!{
      $\!foo
      $\\!foo
   i was confused.
   -------------------------------------------------------
   Contrast this with regular escaping, where \ precedes $:
      \$foo
      \$!foo
      \$!{foo}
      \\$!{foo}
  This renders as:
      \$foo
      \$!foo
      \$!{foo}
      \bar

  My output is:
      $foo
      $!foo
      $!{foo}
      \bar

  it seems like clerical error.
