When I write OO-Perl, I use inside-out objects, and I find myself frequently typing up lists of very simple accessors like the following: 
  sub foo : lvalue { $dat{ +shift }->{ 'foo' } }

Today I got fed up with the COBOL Fingers effect and wrote a tiny filter which lets me type 
  dat_attr foo;

[download]
...which is filtered into the original version above.

Surely, surely it's been done before, in an even more elegant and intuitive manner, right? I glanced through Class::Accessor and its derivatives, but they're quite robust, so I didn't find anything as trivial as this.

So what's my faux pas? My maxima culpa? How many Perler Nosters does this warrant? Ave Larrias? 
package Class::Attr::Lvalue;
use Filter::Simple;
FILTER
{
   s/(\w+)_attr (\w+)(\s*);/sub $2$3: lvalue { \$$1\{ +shift }->{ '$2'
+ $3 } }/g;
#   print;
}
1;
