use Filter::Simple ??? are you serious?

absolutely, makes things much nicer

use base 'Devel::Declare::MethodInstaller::Simple' ??? are you serious?

absolutely, its for those who want sugar but not source filters -- schwern says its reliable

nice but ... - overhead by extra sub call

HA! are you serous? You can't be serious :)

- parameters are unpacked into %p hash, i.e. you need to type $p{x} to access x

this isn't the only usage, there is validate_pos, and even as Attribute::Params::Validate

and you'll miss all the benefits of compiletime checks for lexicals like my $x.

What compile-time checks?

So any serious arguments other than clicking thru CPAN?

You're looking for arguments about something? About what?

Hey look, these are compile-time :) fields, Hash::Util::lock_keys, Sub::NamedParams

If you're referring to so which pattern do you think is better? to me there really isn't much difference between them -- not that your mission makes sense to me

Even if I'm typing this stuff myself, I'm fine with

defined $pos1 or die "missing arg"; defined $pos2 or $pos2 = 42;

but I wouldn't mix that and  my ($name1,$name2) = @arg{qw/name1 name2/};

I would use a hash or a flatlist
