Subject: Re: How to use a hash inside a Struct?

I think both of these methods will work

Thing = Struct.new(:attr1,:attr2,:attr3)
t = Thing.new(Hash.new, nil, nil)

and...

I was thinking that the attributes in the structure had to be typed
first (a bit of c left in me). But it makes sense that I can set up
the attribute and put whatever I want there.
The second method looks a bit RubyTk'ish. I wonder if RubyTk uses OpenStruct.
Anyway, Thanks. This is just what I was looking for
