Re^3: Can @_ be extended?

A better grade of magic here. This is closer to what I was hoping for when I asked the question. Must be all that 'tolkien' in the air. My own preference would be for local and since I am both the 'personal' and the 'corporate' in this context it's a win no matter how I do it. Life is nice when you work for yourself---now if there were only money in it!??! Thanks BrowserUk

Update:
I note that this:

sub setmode ($\@) {
    our (@array,$val);
    ($val,*array) = @_;
    splice (@array, 1, 0, $val);
}
[download]

works as well.

I note that this: ... works as well. Yep. Though I would write that as: `sub setmode ($\@) { our( $val, @array ); local( $val,array ) = @_; splice (@array, 1, 0, $val); }` [download] Ie. Order the values in the our to match the prototype, and localise the globals so that when you call this function from another that also uses one of the globals $val or @array, you don't stomp on their values by mistake. There are various aiasing* packages on CPAN, but they mostly (all?) only allow you to alias similar types, which is different to aliasing a array name for an array ref as we are doing here. Examine what is said, not who speaks. Silence betokens consent. Love the truth but pardon error.	[reply] [d/l]
