"Using a hash as a reference is deprecated"

I guess I don't get what you mean from what you write. Could you provide a code example on how that's done?

I know of hashes, and anonymous hashes, and taking references to a named hash, and passing around hash references (i.e. scalars). But "using a hash as a reference" sounds to me like some not-yet-heard-of magic of evaluating a hash (in scalar context?) and getting a reference to a hash thereof. Hmm.

--shmem

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}

I didn't know about this either, but I just looked it up and it appears you can use a hash just like a hash-ref and it will work (but give that warning): `perl -Mwarnings -Mstrict -e'my %a = ( a => 1); print %a->{a}' Using a hash as a reference is deprecated at -e line 1. 1` [download] "What should it profit a man, if he should win a flame war, yet lose his cool?"

Wow. I wonder how much thought and discussion went into this dwimmery now deprecated? What more of the like is in perl that I don't know? I'm unable to interprete the shudders runinng down my back after knowing this right now. Pleasure? Fright? Have to work that out... --shmem _($_=" "x(1<<5)."?\n".q·/)Oo.

What more of the like is in perl that I don't know? got me thinking, so i tried it with an array. wacky! % perl -Mwarnings -Mstrict -e 'my @a = (1); print @a->[0]' Using an array as a reference is deprecated at -e line 1. 1	[reply]
