Re^2: Longest repeated string...

A list in scalar context returns the number of items in the list. Not quite.

A list assignment in scalar context returns the number of items in the right-hand list.

japhy, Thanks - which is why I said this deserved an entry in "Perl Idioms Explained". I could argue that there is no assignment going on in: `while ( @array ) { ... } # or print "Array is empty\n" if ! @array;` [download] but then we could discuss the difference between lists and arrays and it wouldn't be worth it. I think I was able to get the OP to understand even if I wasn't completely accurate. I do think it would make for a good entry in "Perl Idioms Explained". Cheers - L~R	[reply] [d/l]

japhy, I am sure you understand it better than I do. I often understand things well enough to use them but not well enough to explain them to others. Be my guest. Cheers - L~R	[reply]
