(jeffa) 2Re: 1 line array to hash converter

The @ sign pretty much tells the interpreter to expect a SLICE, and since hash is (hopefully) already defined as a hash, you get a hash slice. :)

japhy has a great little 'tutorial' i found (via google) at http://www.crusoe.net/~jeffp/docs/using_refs

Actually, it's the type of brackets - {} - that tells Perl that's it's a hash slice. -- <http://www.dave.org.uk> "The first rule of Perl club is you don't talk about Perl club."	[reply]

Just because your statement confused me a little: The type of brackets - {} - tells Perl that it's a hash. The @ tells Perl to use list context vs. scalar context. Note the difference between: `@hash{@array} = (1) x scalar(@array); print join(" -- ", keys %hash), "\n"; #AND $hash{@array} = (1) x scalar(@array); print join(" -- ", keys %hash), "\n";` [download]	[reply] [d/l]
