Yes, compare that to the smallest possible, ISO-compliant burst laughing C++ compiler implementation in any language...
Complicated means "likely full of errors that are hard to identify"...
Your Forth implementation is fascinating.

ETHZ still uses Active Oberon somehow,
https://gitlab.inf.ethz.ch/felixf/oberon
This is the owner of that repo,

However I do agree it is very niche, one is better of with Go, D, C#, Swift, as modern compiled managed languages with low level language features for systems programming.

Commercially it had some popularity in industrial automation and robotics many years ago and some companies still maintain Oberon codebases for this reason. I believe this is the main target market for the commercial Astrobe Oberon compiler for Cortex-M, which sells enough to stick around.
I can’t think of a good reason to start a new commercial product in it and I’m not aware of any new commercial uses, but there are still lots of academic and hobby projects cropping up.
