138 There are only a few attributes currently handled by Perl itself (or
140 package-specific attributes are allowed by an extension mechanism.
143 The setting of subroutine attributes happens at compile time.
144 Variable attributes in C<our> declarations are also applied at compile time.
145 However, C<my> variables get their attributes applied at run-time.
147 before those attributes will get applied. For example:
