> Do you mean just writing "find([ 1, 2, 3 ]) x: x > r" with explicit () and explicit variables? I agree that is easier to read, though the extreme terseness is also a feature.. Yes, amd yes it depends on the purpose. For learning, it can be impossible to parse; redundancy helps distinguish parts and provides a check you got it right. OTOH for showcasing features, IMHO, the generality of : is a more impressive feature to demo. Anyway, it's certainly intriguing! And maybe that's the true purpose of showcase code...
