no Doom running on cel.
I recently wanted to expose some basic user auto tagging/labeling based on the json data.
I chose cel, over python, SQL because I could just import the runtime in C++, or any language that implements it (python, js etc..)
Safely running a sandboxed python execution engine is significantly more effort and lower performance.
At this cel excels.
Where it didn't was user familiarity and when the json data itself was complex.

"Guaranteed to terminate" actually means "guaranteed to terminate in finite but possibly arbitrarily large time" which is really not a useful property.
There's no practical difference between a filter that might take 1 billion years to run and one that might take more than a billion years.
