__usedindex in 5.1???

[Chris Marrin <chris@...>]

I am new to Lua and am currently working on integrating it into a C++ 
app. I was very pleased to see incremental GC being integrated into 5.1 
because our app has some real-time constraints.
I also need to have better control over property access, which would be 
accomplished with the __usedindex patch I saw on the power patch page. 
Is there any chance this will get integrated with the 5.1 source base at 
some point? Is there any chance it will be added? Looking at the patch 
it does not seem like it would be much of a performance hit and it 
doesn't look like there would be any compatibility issues. I would much 
rather use a clean release than patching.
thx
