The syntax strikes me as a little clunky, but I do like the idea. Coming from Python I’ve used generators a lot (which in my obviously biased opinion is a clearer name that “iterator” here) so recognise the value in having something like that in the language.

Same feelings / background here. Navigation will take me a little to grok, but I’m liking it so far.

Why would it be illegal? It’s shitty and it’s obvious what they’re trying to do, but I can’t fathom what law from any jurisdiction this would violate.
