Yes, a very good feature set "to have". I think, at this point not even half of them are implemented. The author is doing a major disservice by presenting as if everything is complete in the main website.
I must clarify, not out of the features listed by GP, but the features listed on the website. No ill will towards you, but the source of all the problems seems to be - how you present the state of language on the website as if it already has all the features noted there. And you seem to have different standards for feature completeness [1], while others expect the feature to be completely implemented, not just a proof of concept with tons of work still required. Again to clarify, I do like the idea behind this language and hope all the best for it.
