I don't think I understand your question. I tried this: 
# snip code

...and that works.

Of course!

Are you saying you want to do something like "$obj->sub { do_stuff(); etc(); }( @args );" so that you don't need an explicit $action?

Exactly, out of orthogonality considerations.

It seems that you're basically doing something like: 
{
    @_ = ( $obj, @args );
    # rest of 'sub' goes here
}

"Inline" code doesn't need to be made into a sub. Am I misunderstanding your question?

Possibly so: I certainly don't understand your reply. Are you saying that you would expect the following to work as (I) intended?

use strict;
use warnings;

use Data::Dumper;

my $obj = bless {}, 'Foo';
$obj->{ print Dumper( \@_ ) }( 'hello' );

__END__

If so, then it doesn't because ->{ is interpreted as hash dereferencing:

$VAR1 = [];
Use of uninitialized value in subroutine entry at 605841.pl line 7.
Can't use string ("") as a subroutine ref while "strict refs" in use a
+t 605841.p
l line 7.

OTOH Anno and grinder completely addressed my question.
