in reply to !Overriding Builtin print

IIRC some keywords can _only_ be overriden from import. I dont have time to test if print() is one of them, but it may be that if this override is done through the import mechanism in a similar way to which glob is overridden in File::DosGlob that it will work.

    No. You are mistaking ->import() for BEGIN. The point is getting the override information to the parser before it parses the portion you expected to be overridden. ->import() can do that because it happens at BEGIN-time during use(). You can do that yourself with an inline BEGIN block.

      Interesting. However, given the documentation on my system this mistake is not difficult to understand... From perlsub

      Overriding may be done only by importing the name from a module--ordin +ary predeclaration isn't good enough. However, the use subs pragma lets yo +u, in effect, predeclare subs via the import syntax, and these names may +then override built-in ones: use subs 'chdir', 'chroot', 'chmod', 'chown'; chdir $somewhere; sub chdir { ... }

      But thanks for the clarification.
