Faster development with an interpreted dynamic language with performance boosts from the JIT and inline Go.
You can do similar things in other languages but not AFAIK as a built in feature. You can have in line C innTCL
the niche I'm aiming for is small tools where I want a dynamic language but Go-like deployment. for example, a CLI app, an automation tool, a webview desktop app, a small HTTP server, etc... and can then be shipped as one executable without asking the user to install the runtime on their machine or manage packages
