Minor point, but your creates %attrs hashes by copying the incoming hash (if any), but it could just use its ref directly. So instead of:

my %attrs = %{shift @$data}

You could say:

my $attrs = (ref($data->[0]) eq 'HASH') ? shift @$data : {}

Then refer to $attrs->{FOO}.

Or maybe

my $attrs = ref eq 'HASH' ? $_ : {} for shift @$data;

which I find a lot less clumsy. Update: was ref $_ before.

Absolutely; I often topicalize with for. But I'd also write "ref $_" as "ref" or "ref()" -- concision!

I don't generally like foo() much for routines that operate on $_. In this case I added it because I'd've had to if I'd written

'HASH' eq ref ? $_ : {}

as the question mark is then parsed as a pattern delimiter instead of as part of a ternary. I usually write my comparisons that way around. But here neither the parens nor the variable is necessary as the following eq is unambiguous as to its meaning.

Oops! Your substitution is actually really broken, because when $data[0] isn't a HASH, it gets thrown away. This is a Bad Thing. I didn't notice it at first, which is also a Bad Thing. :-,

I knew full well about that, but didn't pay close enough attention to know it's undesired. Also a Bad Thing..
