in thread Never lock $0 inside of a BEGIN block

Furthermore, I completely disagree with your statement Perl has miserable error messages.

Blush. Im sorry. Misserable is much stronger than I would have said if it werent for the bizarreness of this scenario.

it's not feasable to determine where a quote is missing, and hence where the unterminated string begins. However, in many occasions, perl manages to make an educated guess that's often quite right.

Why isnt it possible to determine where the quoted string began? Why does it have to "guess"?

    Well, you were generalizing. The following remark isn't limiting itself to a specific scenario:

    On a bit of a grumble side, IMO one of Perls biggest weaknesses is its absolutely terrible error reporting. The messages are usually misleading and often just plain old wrong.

    Why isnt it possible to determine where the quoted string began? Why does it have to "guess"?
    Because in most cases, a program consists of more than one string. Say you have 20 double quoted strings in your program, and you forget to close one of them. So, Perl sees 49 quotes. How's perl to know which 20 of them start a string, if it cannot assume the sequence is "start string", "end string"? After all, strings can contain newlines.

      No wonder the poor thing is confused:)

        Well, yeah, didn't you see the 10 references to $"?
