I'm adding a missing typed array, the Uint8ClampedArray. You can see the changes at https://github.com/mikeseven/node/commit/27ad75f882a6c7ad06a878f3eaab292a045ffc4c I didn't put this in the pull requests yet because I have an issue with the syntax: buf[idx]=value, which should do the same thing as buf.set(idx, value) that works correctly in this commit.
Does anyone know where buf[idx] is handled?
