Re^4: basic question:how to print a reversed array from STDIN

No - map returns a new list, so changing $_ makes little sense. Either use a foreach if you want to do an inplace modification of a list or return a fresh list and try to keep away from changing the list alias :)

Yes, if you take care about the list on the right hand side. But, consider this: `map { s/^.//; } grep { /^[abc]/ } @somewords;` [download] holli, /regexed monk/	[reply] [d/l]
