PLugins able to call functions in Lua tables

Would it be possible for triggers to call functions in Lua tables? Ie:

demo = {}
demo.test = function() world.Send('blah') end

<trigger
...
script="demo.test"
...
>
</trigger>

Or something along these lines? It's easy enough to work around by simply making duplicate functions that are callable by triggers, but thats so messy...

This is implemented in version 3.75.
