Looks very nice! The templating and server support makes Lily look like a nice "next step" for PHP developers/shops/projects. PHP's "installed everywhere" feature is pretty hard to beat, especially for host-it-yourself projects like Wordpress. I could see such a language catching on for custom, in-house development though; for example to implement microservices.
It's nice to see that there's a trend for such small, (relatively) simple languages to include nice features like first-class functions, convenient lambda notation, sum types, type inference, etc. A few years ago it seemed most new languages were just nitpicking over syntax, without bringing much to the table. I'm glad to see we're leaving the local minimum of "class-based OO with slight different static method mechanism"!
