For more than twenty years now I am roaming the frontier between the database query and programming language fields. During all that time, one trusty companion has never let me down: the comprehension. Its elegant, concise syntactic form and flexible semantics render it one of the most versatile tools in query and collection processing, analysis, transformation, and optimization. I will highlight a variety of places where the DBPL community has dependend on comprehensions — and will also point out how existing work might have turned out differently if it would have embraced comprehensions. Comprehensions glue DB and PL together. Give them a proper hug the next time you encounter them.
