Oh, well. That would make my logging much harder.

|unit
|   Foo;
|
| ...
|
|const
|   MODULE_PREFIX = 'Foo.';
|
|procedure Foobar;
|const
|   PROC_PREFIX = MODULE_PREFIX + 'Foobar';
|begin
|   ...

I would have to declare a different name for each subroutine and they 
wouldn't have the local scope (in case the subroutine gets refactored, 
the log name should also be changed).

Names of nested subroutines would be almost impossible to maintain.

Of course, this is of no practical use. It's just in about 70K lines of 
code of a real world project. Yes, I'm being a bit cynic here.

Regarding class constants: I missed them, too, already, although not too 
much. ;)
