def executer(obj, method)
obj.send method , 1
end

class X
def test(x)
p x
end

Thanks for your help. I got it and it works fine.

Another question:
Is there some ruby reference on the web, something like
http://api.rubyonrails.org/ for example?

Then you can use instance_method(), which is like method() except it
returns an *unbound* method:

def executer(obj, unbound_method)
unbound_method.bind(obj).call(1234)
end

class X
def test(x)
p x
end
end

o1 = X.new
o2 = X.new
o3 = X.new
method = X.instance_method(:test)

executer(o1, method)
executer(o2, method)
executer(o3, method)
