Re: dereferencing syntax question

That would work. I would probably prefer to modify the param method and have it return a list in list context so that

    my %CF = $self -> param ('CPref');

just works. But then, I don't know how 'param' is used in list context already, so it might not be feasible.

Thanks to BrowserUk and pg for the fix and the concise reason why. Abigal: param is from CGI::Application module. I'm planning to use as is and not override it. ------------------------------------- Nothing is too wonderful to be true -- Michael Faraday	[reply]

Returning a hashref is a lot more efficient than a hash, because of all the flattening Perl does to the hash when passing one back from a subroutine. In a CGI program, a method like `param()` could be used a lot, so it's important to optimize it. ---- I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident. -- Schemer `:(){ :\|:&};:` Note: All code is untested, unless otherwise stated	[reply] [d/l] [select]

That's why I said I would change it to return a list in list context. Returning a hashref may be more efficient, but if you flatten it to a list right after returning it, you've lost most of your gain. Abigail	[reply]
