The pros are summarised here:

The main cons would be the lack of LuaJIT, the lack of C or C++ bindings, and the fact that Lua is spectacularly more mature and stable :)

Depends on what type of syntax you enjoy I think.

Functional language approaches are very neat to encode game rules. Just define the sets to which a rule apply, define rule -> behaviour maps and then apply. With this alot of procedural/object orientated cruft shrinks down to one page algo&definitions.

Lua does supply this style, just needs some slight additions.
