no-loop implementation

[pablotdl]

Hi,

would it be possible to implement the no-loop clause in the DSL so that a rule is not re evaluated as a consequence of its RHS expression modifying the facts?

That'd simplify rule creation a great deal for some use cases.

Thanks in advance.

I am in the process of submitting a pull request that implements no-loop.

Excellent!
