I was just wondering if anyone has come up with any helpful elisp or slime/swank customizations that are helpful to edit quasi quoted expressions (and therefore authoring macros). I tend to get lost when things get much more deeply nested than ,', and so forth, and I was just thinking how useful it would be if there were some visual cues to help identify/correlate ' with the operative , and to indicate where the position of the cursor or current form represents in the layers of quotation -- maybe somewhat analogously to the concept of highlighting of the s-expression for paren matching.
