[Python-Dev] Let's just keep lambda (original) (raw)

Which reminds me, we need to support roman numeral constants. A silly implementation follows.

class RomanNumeralDict(dict): def getitem(self, key): if not self.has_key(key) and self.isRN(key): return self.decodeRN(key) return dict.getitem(self, key)

def isRN(self, key): for c in key: if c not in 'MmCcXxIiDdVv': return False return True

def decodeRN(self, key): val = 0 # ... do stuff ... return val

Huh! Was someone bad-mouthing lambda again? We should keep it, but rename it to honor a different Greek letter. xi is a good one, easier to type, and would lay solid groundwork for future flamewars between xi enthusiasts and Roman numeral fans :-)
