Re: Re: What's the idiom for finding and removing the found @ARRAY element?

Good point about the reverse, if I was removing more than one. That's what I'm doing, but returning out of the loop as soon as I found it.

Now, can you apply the $# syntax to a reference? My brain gagged at that, even if Perl wouldn't (I went with scalar -1).

Sure, that's what curly braces are for. (Well, one of the many things.) `for my $i ( reverse 0 .. $#{ $ar } ) { splice @{ $ar }, 0, $i; }` [download]	[reply] [d/l]
