Yeah, I agree — LET and LAMBDA are surprisingly powerful. They definitely help with naming intermediate values and avoiding recomputation.

The limitation I keep feeling is less about expressiveness and more about working with existing formulas: debugging, making small changes, or explaining intent to someone else.

Even with LET/LAMBDA, the structure still lives mostly in a single line of text, and the formula bar UI doesn’t really help you reason about that structure. That’s the gap I’ve been curious about exploring.
