Who is going to remedy this?
At what time?
How do prototypes remedy with this?
Are you thinking of signatures?

Perhaps that's a question for the original commit including that statement? Althought history seems to stop here: 823edd9
It seems however to refer to standard prototypes and not the new signatures.

My point was more that the vibes are wrong. Optimistic use of future tense and prototypes really don't mix in $current_year

It's definitely not a change we will be making. That sentence should be removed.

Oh yes please remove it or whatever and also tweak my version if you want I'm very welcome.
I guess I'll learn what a version bump is a little later. But just go right ahead.

\( ... ) is a list of references to each of the items in the parens. \( @things ) is not a reference to @things, nor a reference to an anon-array with the items from @things:
% perl -MData::Dumper -E '
say Dumper \( @ARGV )
' -- two items
$VAR1 = \'two';
$VAR2 = \'items';
\( %things ) does the same with the key/value pairs from the hash:
% perl -MData::Dumper -E '
my %arg = @ARGV;
say Dumper \( %arg )
' -- one pair
$VAR1 = \'one';
$VAR2 = \'pair';
Dumper \(%a, @b, $c) is not a good example of how to avoid list flattening.
