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
You can do similar things in other languages but not AFAIK as a built in feature. You can have in line C innTCL
