I believe your second example (which is always the way i call methods and subs now) is something that is almost exclusive* to Perl because of the concept of lists. PHP can't even do this "out of the box" like Perl can, observe:
my $circle = Circle->new(
radius => 4.5,
origin => array( 2.3, 2.2 ),
visibility => 1
That's right ... PHP methods do not accept a list
of arguments -- you have to make your array and pass it to your method. Now, you can
use named args in PHP but they are still positional, meaning that you can't pass the args in an arbitrary order. In Java you would need to first instantiate a new Hash object, fill in its values and then pass that to your object's constructor. Yuck!
All of this just reinforces my belief that 9 out of 10 Perl haters only hate Perl because they just don't get it. I myself am no fan of Perl 6, but it is good to hear that named parameters are now default.
*I haven't bothered to read up on it, but i'll wager $50 that Ruby and Python can handle this.
UPDATE: Duh! Lisp! Thanks for setting me straight Porculus. :)
