| Hello Dirk,
| Where would you choose to use parseEvalQNT() instead of parseEvalQ()?

Please see examples/standard/rinside_sample14.cpp for one example. If you use
the throwing variant, you "jump".

Well "it depends" as it always does. 

So I provide an API with different options.  You get to pick.

Hth, Dirk
