Need Help??

Do you call this
```
sub tail (@) { shift; @_ }
[download]
```
functional programming? You clearly rely on the side effect of shift here. Better use
```
sub tail (@) { @_[1..@_-1] }
[download]
```
or something like that.
Please do not make links to your scratchpad from your post. The data from will most probably disappear eventually from the scrartchpad, but the post will live forever so if someone reads it years later he'll be upset than he cannot see the code.

re: #1 You are absolutely correct. Good eyes there. Of course if we are gonna be picky, then `head` should be: `sub head (@) { $_[0] }` [download] to also avoid the "side-effect" effect of `shift`. re: #2 I see what you are saying here, but approx. 300 lines of code IMO, is not really appropraite to post in a node. As for posting the code elsewhere (website/CPAN/whatever), it was really just an exercise for fun, to see how far i could push Perl into the realm of functional programming, I have no delusions that it is good for anything outside of that. -stvn	[reply] [d/l] [select]

The desire to have more data in a node than people want to see scrolling over it is what READMORE is for. Read more... (145 Bytes)	[reply]
