There are major concerns with using Attributes (particularly ones that use Attribute::Handlers) in combination with mod_perl. This is due to the fact that Attribute::Handlers uses CHECK blocks (by default, anyway) to set up the subroutine attributes and CHECK blocks don't run under mod_perl. Thus, the symbol table approach is not dependent on compilation stages and is sure to be in place at runtime.

This is not a new concept -- for example, Module::Build internally marks actions callable from the command line with the prefix "ACTION_". (E.g., "sub ACTION_test"). Its dispatch function just checks that it can("ACTION_$request") and subclasses can add new actions just by adding methods called "ACTION_whatever".
