I would like to understand how Guidance compares to LMQL when reading the docs. Can we gather a list of additional features?

People should feel free to leave notes here. The core of Guidance was written before LMQL (but not widely released), so the design choices were made independently and I expect there is stuff to learn beyond just the fundamental difference of a template language style vs. a SQL database style.

Makes sense! Happy to start creating a list.

Do I understand correctly that LMQL especially does not allow pattern enforcing in inference?
