I've never used this particular library, but I did put together my own simple evaluation engine and have found it very useful for a range of purposes.

Initially it was designed to process incoming slack messages, and sometimes trigger a notification to an on-call engineer, but over time I've found uses for it processing email, scripting simple actions on my desktop, and more.

These kind of things are pretty simple to write, but sometimes I almost think it is a shame there isn't something more standard. (Lua was kinda winning for that embedded-logic role for a long time, but nowadays we still have the mixture of YAML, HCL, and other niche-specific language/filtering and I imagine the time has passed to pick one standard.)
