Dynamic rules do not work in interpreter in the testing language.

E.g., the test

test dynamic rules
rules(DR := 1)

puts this exception in the error log:

Could be the reason why i have similiar problems using the namespace libary and testing

Dynamic rules don’t work in test expressions right now since they need a more sophisticated compilation scheme. This issue shouldn’t affect any dynamic rules defined in the project under test though.

Note that this issue also applies to the console.
