LGTM.

src/ast.cc:240: void* key;
Could this be made an Object** since that's what .location() returns?

Not without some reinterpret-casts.
There isn't a simple conversion from String** (which is what this location()
returns) or Smi** to Object**. The use of the value is in table->Lookup which
expects a void*.
