Even PHP had a composable expression syntax (e.g. nested arithmetic/string/array expressions, function calls, etc). I don't think this does; every statement seems to be a unique, standalone thing.

That may be a good thing. I think it's more natural to have it that way. I always wondered why a keyword in a programming language must have this rigid meaning. In English, that's not the case, there's a context.

Gliimly seems much simpler than PHP or other "classic" programming languages out there (C++, Java, Go, whatever). I think there's something to the idea of expressing programming closer to English, in a declarative way.

I'll give it a try, I'd love to type (much) less and just sort of "talk" programming, because that's what this looks like.

I don't see how foregoing composable expressions makes the language any more like English or more natural. Gliimly is like Assembly (generally seen as very "unnatural"), if it had fewer cryptic mnemonics and more SQL-like complex commands.
