Would you do:
  GOOD = "good"
  SIN = "sin"
  COS = "cos"
and use the 'constant' variable for assignments and comparisons? I  
realize the foolishness of that, but (even without a hack to holler  
if I read an undefined global) it somehow feels cleaner than just  
hardcoding the same literal strings in many places in the code.

For sure. That's not an option in my actual situation, though. I just  
liked the sin/sin comparison and reached hard to make something up :)
