Do you think of a comment inside one line of code? This is not really
possible. But you could do it as follows:

before:
  3 + 4 + 5 + 5 - 4 - 5 

after:
  3 + 4 + (%{5 + 5 - 4}; - 5)

Better is to copy the line and comment the duplicate out. Then modify
the other.

Simply start with a string (or integer) of an arbitrary length (e.g.
"dlkjddfdfd"), then each time you want to generate a new ID, simply call 
aString.succ!
