Thanks! In the Scribble documentation, section 2.4.1 introduces 
alternative body syntax `@|whatever{ ... }whatever|' for @-expressions, 
but it wasn't clear to me from section 2.4.3 on comments that this 
applied to comments (though I suppose it may be implicit in the 
parenthetical remark "following the same rules for @-forms"). --PR
