One significant problem with this is that, you loose alot of 
static introspection and reasoning capabilities.

As you need not only understand the core concepts of the language 
but also the specific dialect written by user-code.

Also while it may look like a reduction of complexity we compiler 
guys have to me even more on our guard if the users can 
manipulate asts too freely.

And it is very easy to write spaghetti-code which looks totally 
harmless.
We are throwing the programmers intuition away if we go the 
"make-a-lanugauge" road.
