If pre and post are always executed directly after eachother, then what's the use of separating them? What part of the story am I missing here? 

use Attribute::Property;

package Cool;

sub new  : New;
sub name : Property { $_ = reverse uc; 1 }

package main;

my $obj = Cool->new;
$obj->name = "My right foot";
print $obj->name, "\n";

[Attribute::Property] doesn't actually provide hooks for pre/post "processing"

It provides a single hook for processing and validation: the code block. The value returned by it determines whether the new value is correct (hence the 1 in the example above), but both $_ and $_[1] are aliases for the value that is about to be set, so there's more than enough chance to manipulate the value before it gets assigned.

It should be noted that I also have no idea what C# does. I tried googling, but found only one sort-of relevant document, which has no examples and no explanation that I immediately grokked.

Juerd # { site => 'juerd.nl', plp_site => 'plp.juerd.nl', do_not_use => 'spamtrap' }
