Method Combination

• Usually, you just want most-specific rule

• Lots of not-so-usual cases:

  • More-specific rule needs to modify return value of a less-specific rule
  • Result Combination
    • sum/min/max of rules' return values
    • first false result, first true result
  • Custom Precedence
    • Sometimes, precedence is unimportant
    • Sometimes, a special sequence is needed
    • Maybe you even want to allow ambiguity!
