I originally had a section about reader macros but I ended up cutting it since the article was running a little long.
Reader macros are great, but they work best when a token can unambiguously be recognized by the reader as using some "special syntax" (usually involves a '#' and then another dispatch character preceding the new syntax).
This is great when you're coming up with a brand-new syntax. But if you're trying to match something that already exists, it's not easy
