That's not surprising - you're only calling the block once (and your
passing in the hash).
You probably want each_item to read
@plugins.each {|plugin| block.call(plugin)}
def rubyfunc
each_item do |item|
puts "Rubyforum"
end
end
def each_item(&block) { block.call(@plugins) }
end

scan = Scan.new(loaded_plugins)

Great, good point!
What if I want to access that certain objects functions ? (i.e.
not having a hash, but converting it back to a real class)
=> Changing the inside function from above:
...
def rubyfunc
each_item do |item|
item.get_another_function(self) <- Wouldn't work
end
end
Any ideas ?
