Also, when the Perl RFC 0001 comes into a stable release, you can write

for my ($key, $value) (f()) {

I guess that this will come in 5.36 as experimental feature and hopefully will leave the experimental stage with 5.38.

Yes, that's the point of this syntax. It wouldn't help for the case of the OP, as the call to `f()` will still generate the whole list.	[reply] [d/l]
