Retrieve names of code references

'Sub::Identify' allows you to retrieve the real name of code references. It provides six functions, all of them taking a code reference. 'sub_name' returns the name of the code reference passed as an argument (or '__ANON__' if it's an anonymous code reference), 'stash_name' returns its package, and 'sub_fullname' returns the concatenation of the two. 'get_code_info' returns a list of two elements, the package and the subroutine name (in case of you want both and are worried by the speed.) In case of subroutine aliasing, those functions always return the original name. 'get_code_location' returns a two-element list containing the file name and the line number where the subroutine has been defined. 'is_sub_constant' returns a boolean value indicating whether the subroutine is a constant or not.
