in reply to $_="eval eval"; s/a/i/;

Highlight to read:
8 e's are required, so 13 e's may be omitted. I notice that 8+13=21 are all Fibonacci numbers. Is that deliberate?
The first e terminates the regex. The remaining 7 e's produce: 
36.95.32

    ... Fibonacci numbers. Is that deliberate?

    Wow, very perceptive, jdalbec! The use of Fibonacci numbers is not coincidental; it's a sort of signature that I use in a lot of my obfuscated code. I meant for it to be a hidden element, but there you go finding it as the first replier!

    I (foolishy) started all this nonsense after posting my first obfuscation, Fibonacci, before becoming a member. The use of Fibonacci numbers in this particular obfuscation is (in all honesty) quite silly.
