Recorder is similar essentially a method probe. It records everthing that happens to it, building an internal parse tree. You can then pass a substitute object and apply the recoding to it. Or you can utilize the parse tree.
The only limitation of Recorder is with special operators, like if, &&, ||, etc. Since they are not true methods they can‘t be recorded. (Too bad for Ruby.)
class Z
def name ; 'George' ; end
def age ; 12 ; end
end
z = Z.new
r = Recorder.new
q = proc { |x| (x.name == 'George') & (x.age > 10) }
x = q[r]
x.__call__(z)
produces
true
