In Lua, if you want to send a message to an object, but only if that
method exists you can do:
if object.message then
object:message()
end
The equivalent in NewtonScript is:
object:?message()
I was thinking if lua had a hook for a ? look whose default behavior was
the same as a "." lookup but could be overridden, this syntax would be
easy to implement in lua...
