Commented Task: addSynSymbol is not defined [13549]

I have tried both the most recent beta and alpha versions of pykd, but it appears that the API function addSynSymbol is not defined. What happened to it? Is the documentation just wrong, and this function is no longer supported? Is there some extra step I need to perform in order for addSynSymbol to be available?

There's not a way (that I know of) to create a synthetic symbol outside of the IDebugSymbols3::AddSyntheticSymbol API function, so the only other option is to write a WinDbg extension in C++, and I was really hoping to be able to write something in Python rather than C++.
