Isn't there already a 'core' here?  Could you not call the VM the 'core'?  I mean, well all your token filters and such could be seen as compilers that output lua binary chunks, and they could just be loaded as is.  It could even be possible to write any arbitrary syntax you wanted and compile it down to LUA byte code would it not?

But actually, I don't think the telescope should be held that way.
Reason is, token filtering will always add onto the loading speed,
even if the modified features weren't even used by the script. That
is bad, and Lua authors value loading speed highly, which is great.

So in my opinion, the benefits of a smaller core would be
overshadowed, and smallness is not an end goal per se.

In fact, I would expect to-be-famous token features to get adopted
into the language, some day, once the use and syntax of them has
stabilized (and more than 50% of Lua users are indeed using such
tokenizers). Maybe, that day will come?
