 There are strong and vigorous conventions for the meaning most operators, such as 
 
-* comparisons (`==`, `!=`, '<', `<=`, `>`, and `>=`)
+* comparisons (`==`, `!=`, `<`, `<=`, `>`, and `>=`),
 * arithmetic operations (`+`, `-`, `*`, `/`, and `%`)
 * access operations (`.`, `->`, unary `*`, and `[]`)
 * assignment (`=`)
 
 Don't define those unconventionally and don't invent your own names for them.
