I was actually talking about existing perl5 here. I write:
my %h = (
x => 100,
y => 75,
z => 99,
);
explicitly writing the "unrequired" comma on the last element
(z=>99). That way, if I add another element to the hash there's
no danger that I will forget to go back and add the comma to
the line above. Alternately, if I reorder the hash elements
(maybe sorting on the value instead of the key) I don't have
to check whether there is now a commaless line in the middle
of the reordered bunch.
