Yes, this is one approached I've considered.
What about this case?
class Test
attr_accessor :a, :m
end
class Test2 < Test
def m; @m end
def m=(val) @m = val end
def initialize; @a, @m = 'automatic', 'manual' end
end
And this one?
class Test
attr_accessor :a, :m
include M
end
class Test2
include M
end
module M
def m; @m end # should this be a property
accessor or not?
def m=(val) @m = val end
def initialize; @a, @m = 'automatic', 'manual' end
end
I guess the rule could be that only redefinitions in the same class/module
transfer the property of being a property accessor.
Another option might be to use attr_reader/attr_accessor. If no parameters are
passed the next method becomes a property accessor. In MRI passing no
parameters is possible and has no effect.
class Test
attr_reader
def m; @m end
attr_writer # this is not really needed as any method whose name
ends = could automatically be considered a property/indexer setter
def m=(val) @m = val end
def initialize; @a, @m = 'automatic', 'manual' end
end

method is just a method?

Alternative suggestion: make method redefinition work in this case, like this:
var engine = IronRuby.Ruby.CreateEngine();
var script = @"
class Test
attr_accessor :a, :m
def m; @m end
def m=(val) @m = val end
def initialize; @a, @m = 'automatic', 'manual' end
end
Test.new
";
var testObject = engine.Execute(script);
var automatic = testObject.a;
var manual = testObject.m;
Console.WriteLine(automatic);
Console.WriteLine(manual); // should print "manual"
Console.ReadLine();
jwm
