Re: inline caching a list-generating sub

Something like this? :-)

sub foo {
    $list = $foo_cache{join ',', @_} ||= [ do {
        ... rest of sub goes here
    }];
    want_array ? @$list : $list;
}

Nicely written, but you're having it return a ref in scalar context, whereas the OP wanted it to behave like a list (which returns the last element). Change the last `$list` to `$list->[-1]` Caution: Contents may have been coded under pressure.	[reply] [d/l] [select]
