Love it. This reads so much better in my mind than SQL. I love how easy it is to abstract with functions.

My one suggestion: use a distinct symbol for assignment and equality, either :=/==, =/==, or even :=/=. I kinda like the Go way of doing things, := assigns and initializes, == is equality (not sure you have a need for = re-assignment, but maybe). But I would definitely warn against = for context-dependent assignment or equality comparison.

You've got "let" so I guess that is kind of a syntactical difference; I guess the trippy part is seeing "=" do equality comparisons.
