Attribute::Handlers -- the practical use?

princepawn has asked for the wisdom of the Perl Monks concerning the following question:

I stared and stared the examples and docs for Attribute::Handlers, but I don't really know what the practical usage of them would be.

Could someone mention how they benefit code that they are developing? Gracias.

glancing over the p5p list over on http://www.perl.com, I see that these attributes are apparently being used in a development version of perl, like so: `our $sv : shared = "foo";` [download] in this case, the shared attribute means that when $sv is being altered (they say written to, but that seems a bit foreign) that all reads are locked out until the write is complete. You now have a method of implementing multithreaded multiprocessor vars. I can't tell you how this locking is achieved behind the scenes, but there's one possible use. reference p5p digest for 06MAY2001.	[reply] [d/l]

Can't think of anything of the top of my head, but it reminds me of what Larry said in Apocalyse 2 about sticking post-it(tm) notes on things. Thanks for the heads-up, it's good to find new and interesting modules that you didn't know were there. $code or die `$ perldoc perldoc`	[reply]
