in reply to Most infamous "Last words":

I voted for string eval. I hate string eval, in any language, because it's misused too often. There are just very few good uses for eval. And a double e flag counts as string eval. I wouldn't mind if string eval had some less obvious syntax. For the very rare valid uses it has, it wouldn't hurt having to go circles to evaluate code.

(I admit, I have used string eval in obfus, like Re: Re: exactly 390 bytes (perl) or One-liner japh (bash).)

    If you ever use require, you are using eval.


    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

      That's of course true, but it's more conciled (then, say, with do file). I'm also quite sure I'm sometimes using modules that use string eval somewhere.

      Also, what I hate most is when eval is used more frequently then it should be, like evaluating the same code over and over again when it would be enough to call it just once to compile a subroutine, and require typically avoids this. (Not all uses of eval I hate fall into this category, I also dislike when eval is called just once per run unneccesarily, partly because it makes eval more known and people will use it in worse situations.)
