DSQL/BLR compilers internals
This post is some raw notes and is not very understandable by people who never worked with this code. In fact, the old implementation was so ugly that it was not simple even for me (who is constantly working in this area) to achieve this result. It needed many tries and reverts, but IMNSHO ended very well. Also, this was a large work that took many time, and I’m just writing some records here.
