        Go the route vim does -- it can build in the interpreters
for ruby, perl, python, -- but it can also load them dynamically --
so if you don't use any of those, you can still edit, but if you
want to use one, make sure the lib is present at runtime...

        A bit like bash's present extensions/loadables I would think.
