Rule with String or Symbol class

[Rod]

Isn't their a way to right a simple rule for a fact that is just a
string or a symbol?

For example, I've been trying to do something like this:

rule [String, :s, m.to_s == 'IdleFinished'] do |v|
puts 'idle finished'
end

That's the best way to write a rule for String. Eventually, I would
like to refine the Ruleby DSL with some convenience features. If you
have any ideas for how to improve on this case please let us know!
