RulesEngine lifetime and thread-safety about rulesengine HOT 4 OPEN

Hello, I'm curious about the thread safety of the localParam. If we aim to record the result of rule evaluation and assign it to a local parameter, could it be overwritten by other rule evaluations with different inputs?

For instance, let's say we construct a rule containing blacklist words. If the text contains any of these blacklist words, we wish to record the offensive word in the localParam and utilize it to generate the FailureMessage.

@Makciek , it is recommended to use it as single instance to benefit from caching of compilation.

Also, it is thread safe, so you can use same instance at same time

@vanwx localParam is like a local variable in code, they do not share reference with any other rule or execution. So it should be completely thread safe

Yeah thanks @abbasc52 . I did write some tests and it's been safe. Also I found some examples on this repo use the localParam to store result state so it's good.
