if its the same, there is only one way

I'm not sure why you mention this since regex matches and comparisons using fc are very much not the same thing?! You even said as much yourself a few posts up ("//i doesn't help in our case since we needed hash-keys").

Let's agree to agree.

You want to disagree with the author of a post about what the post means... ok. How very special of you.

Misread :(
