Minorly, (although not yet exposed) this also allows the Query impls to no the "source query location" of all parameters (important for the tools). 2) Native-SQL query "translations" are now cached.

This class, for example, is now used exclusively within the query plans to determine the proper "parameter locations". Essentially, it is a very simple parser with a small pre-defined number of recognized tokens. Have a look at org.hibernate.engine.query.ParameterParser and especially the different impls of org.hibernate.engine.query.ParameterParser$Recognizer. Anyway, all this is still not completely done to my satisfaction, but it's a good start. Because these are some very broad changes, I will plan to go with a 3.1rc3 including this stuff (maybe late next week). The current plan is that 3.1 final will then be the release after that. P.S. part of these changes required a modification to the constructor for AbstractQueryImpl to add a new parameter.
