Tough some are easy to use and hard to install :) The latter is less
important imho, when a module is hard to install it's usually justified
somehow, and most of the time the community revolving around it will be
prepared to help.

To go further, I certainly wouldn't mind an app taking 500mb if it does
everything I want it to do fast and well.

Which is why imho for anything non-trivial things must be pre-compiled, and
after that one can start discussing the ways in which different modules can
unload some templates to save some memory, or do various things to increase
their caching. <dream>It would be great if this was handled consistently
accross all templating systems so that improvements there would benefit
everyone. It doesn't seem impossible given that all that's stored is some
Perl code and perhaps some metadata.</dream>

extensibility yes, but sub-classing is only one way to do that, and not
always the best.

Until you've written your own you can't understand just how hard it is. I'm
slow so I had to write three half-baked ones before I got it, and I'm very
glad I didn't release them... There are times when "release often" doesn't
apply all that well :)

Agreed, but that probably won't happen...
