POD doesn't capture code semantics

Last night, not for the first time, I found myself irritated that POD  
has no semantic concept of the code it describes. POD's a great markup  
language but it'd be nice if it were possible to associate chunks of  
POD with bits of code. Instead of

     =head2 C<foo>

     foo is a method...

     =head2 C<bar>

bar is a subroutine...

why not

     =method foo

     =sub bar

?

For formatting purposes =method and =sub could just be macros that  
expanded to =head2 C<$1> but it'd be far easier to extract, e.g., the  
documentation for just a single method if there was a formal  
relationship between POD directives and the things they described.

Of course I realise such a thing would break every POD tool in  
existence...
