But their actual power isn't being made use of the way it should be.

I disagree.

In my book, pluggable keywords "should be" used not by every other module. Their real power is that they allow modules to do the syntax experiments that would otherwise need to happen in core, or that would require source filter (which have such a bad stigma that nobody wants to use modules based on source filters. With good reason).

You could argue that the many different object systems on CPAN make life harder for the casual programmer, but without them we wouldn't have seen the rise of Moose, which IMHO is beneficial for the whole Perl community.

I guess syntax extensions will evolve the same way: there will be many experiments, and after a while some will emerge as quasi standards. If they mature, and impose little performance penalty, maybe they will be merged into "core" Perl at some point. Or maybe not.

So the real power of syntax extensions comes from moving the language design from p5p to the community as a whole. Which is a very good thing.
