Is eval a code/design smell?

  |   | | 37547 [elanthis@aw ] You are right, of course.  There should be a way to make Ruby do what
  |   | | + 37578 [avi@be a4 co] I utterly disagree.  If you are *not* dynamically generating code, you
  |   | | | 37633 [elanthis@aw ] You are missing the point entirely...
  |   | | | + 37637 [gnhurst@hu s] I think you would like Python, which takes this kind of erector-set approach.
  |   | | | | 37656 [elanthis@aw ] If I liked Python better, I'd be bitching on Python's lists to add the

  |   | |   37634 [elanthis@aw ] If eval() is running faster than your schema->lib functions, then I
  |   | |   37648 [tobiasreif@p] ?? I'm not using eval. I'm saving the generated lib as a file; then each
  |   | |   37657 [elanthis@aw ] Ah, I see.  Yes, Ruby doesn't let you get around that too easily, since

  |   + 37536 [avi@be a4 co] Hmm, I don't think it was me - after all, the language *does* provide
  + 38034 [ian@ca ib n.] So what is a better way to do this?
    38045 [elanthis@aw ] Sorry if it should be obvious, but what is the purpose of eval on attr?
    38061 [ian@ca ib n.] Without the eval, the yield method will pass the variable's name to
    + 38062 [pbrannan@at ] Not all instance variables begin with an "@", so this doesn't quite work
    | 38070 [ian@ca ib n.] Just to go off at a tangent here for a moment, why is this?
    | 38071 [decoux@mo lo] in ruby, yes but in C you can create (and retrieve) instance variable
    + 38063 [elanthis@aw ] Ah, got it.
      + 38064 [decoux@mo lo] ???
      | 38066 [elanthis@aw ] Class, object, same difference.  You know what I meant.  (Sorry,
      | + 38067 [decoux@mo lo] this is why eval is evil :-)
      | | 38068 [elanthis@aw ] Ah, I see.  ^,^  So, then, is this a "security bug" in Ruby, or by
      | | 38069 [decoux@mo lo] not a security bug

      | | | 38114 [ian@ca ib n.] Because I'm still learning the language and hadn't discovered it yet :-)
      | | + 38079 [alan@di ik t] Ruby's protection scheme is not intended to procted the encapsulated
      | |   38082 [pbrannan@at ] The difference is that with C++, friends have to be declared by the

      | |   | 38088 [pbrannan@at ] It's more than that.  In C++, bypassing the access control is undefined.
      | |   | 38090 [elanthis@aw ] Ya, well, still - the point is, it's possible, whereas in Ruby (assuming
