Not to disagree with you, but - what "modern" alternative would you recommend as a replacement for "wapptclsh", which is a compact statically-linked binary with wapp and sqlite libraries baked in?

Binary "wapptclsh" + your .tcl script + optionally .sqlite file, just 2-3 files are sufficient to make an app chroot/jail/container, if I understood correctly section 2.0 here: https://wapp.tcl.tk/index.html/doc/trunk/docs/compiling.md

For those concerns, I'd say Go. You can statically link in any pure-Go library trivially. SQLite specifically may require a C file because of its nature, but for accessing databases that take network connections there's a pure-Go driver for most things you've heard of, and there are other static database options for Go if you want them (though they tend more towards NoSQL; if that's really a problem personally I'd just bite the bullet and include the SQLite's library).
