in thread substring search in an array of arrays

Don't pretend... Don't pretend...

I'm not pretending anything. And don't tell me what to do...explain why...with examples.

    Sure thing. An example where the confusion leads to a difference would be $_[0] =~ "Dr.". It doesn't search for "Dr.", it searches for a three char string starting with "Dr". I mentioned split because split '|', ... is a similar common error and a reference to past threads on the topic.

      In other words, whatever is on the RHS of =~ acts exactly like a regex...regardless of whether it is in // delimiters or "" delimiters. Or even if it is contained within a variable. That's exactly what I thought.

        I didn't doubt that you knew. Considering how many people get messed up over split's first argument, I figured the extra clarification of using // over "" is warranted, if not for your own benefit, for that of the person receiving your help and that of the person reading and maintaining your code.
