Subject: Re: Using a block to configure/initialize a class

Hi! thanks for you replies. I'm going to analyze them. For the moment i 
wanted to answer the question of the unnatural api. The reason i wan't 
to do it that way is because i'm not going to use String or array for 
most of the options, but Structs. So i want a way to let the user do 
this

Struct.new "Value", :sub1, :sub2, :sub3 << In fact, the user may not 
even know about the Struct::Value class.

class Options
...same as before...
define_option :an_option
end

opt= Options.new

opt.an_option do |o|
o.sub1= ...
o.sub2= ...
o.sub3= ...
end

instead of

an_option.sub1= ...
an_option.sub2= ...
an_option.sub3= ...
