That looks reasonable enough.  I gave you some feedback on IRC.  I think
the v-table init code can be generalized, but otherwise there's nothing
objectionable here (even though I'd rather not use vtables in the plugin
interface itself).

You've made design choices (e.g., no required/optional plugin entry
points) that make the code generation aspect of my proposal unnecessary.

The key is that you retain strong type checking.

Cheers,

Nico
