[chuck-users] User-defined UGENS?

Just checking in to see how things are progressing (checking in with an ulterior motive: a development project that none of my current tools deal with well, but that fully implemented Chuck would deal with beautifully. Question: Have user-defined UGENs been implemented yet? The docs say no, but I do know that the docs don't always keep up with the reality. Supplementary Question: Have external objects (plugins/loadable UGENS implemented in native external DLLs/libs) been implemented yet? The docs say yes, but the last time I checked, the implementation had been orphaned.
