in thread Simple Hash Q.

I was doing it as a CGI on a CobaltRaq. The error log just gave me grief about the cgi-wrapper without telling me what the problem was.

Likewise use CGI::Carp qw/fatalsToBrowser/; didn't tell me anything useful either.

Regardless, I don't know that that particular error message would have told me that {} vs () was at fault.

    Here's the trick: verify that all of your CGI scripts run from the command line before you run them through a browser. If you must run it through a browser, don't forget use diagnostics and try running it without a wrapper that might mask the errors.
    I don't know that that particular error message would have told me that {} vs () was at fault.
    Well, the error message would have mentioned a couple of things: one, which line number the problem was on. That's very important. Two, once you are more familiar with Perl, you'll see that a list is wrapped in parens () and that braces {} will return a reference. Once that becomes more ingrained, error messages like that will make more sense.

    Cheers,
