__mul()

[Christopher Eykamp <chris@...>]

If this works:

   newpt = bot:getLoc():__mul(2)

Shouldn't this:

   newpt = bot:getLoc() * 2

Instead I get an error:  "attempt to perform arithmetic on a userdata 
value."

Some quick background: bot:getLoc() is a C++ method that returns a 
pointer to a point stored in C++.   I am binding Lua and C++ using 
Lunar.   __mul() is a method added in Lua (I have also tried adding it 
via C++).  How can I get arithmetic methods to work on userdata?

Any ideas?

Thanks,

Chris
