Re^2: Using ternary operator as lvalue in push

It's a hard-wired limitation of Perl 5, but you're not going to have to live with it forever because it's fixed in Perl 6. The way we fixed it was by not committing to scalar/list distinctions until the argument list is actually bound to a function. When we do this, most of the problems of Perl 5's prototypes simply evaporate. In fact, this works fine in pugs:

    my @x = my @y = ();
    push (False,True).pick ?? @x !! @y, <a b c>;
    say "x: @x[]";
    say "y: @y[]";

and randomly pushes the list onto one array or the other.

well, I also expect something like this to work in Perl 6: `($cond ?? @x :: @y).push(<a b c>);` [download] which is a lot more understandable syntax in my opinion. cheers, Aldo King of Laziness, Wizard of Impatience, Lord of Hubris	[reply] [d/l]

As a matter of fact it does: `pugs$ cat prova.pl && ./pugs prova.pl my @x = my @y = (); ((False,True).pick ?? @x !! @y).push(<a b c>); say "x: @x[]"; say "y: @y[]"; x: a b c y:` [download] At least now! Flavio perl -ple'$_=reverse' <<<ti.xittelop@oivalf Don't fool yourself.	[reply] [d/l]
