Experimental ActiveRecord code that DOES NOT FUCKING WORK

experimental_active_record_scope_chain.rb

# In Rails controllers you often chain scopes together, often the chaining is
# subject to certain conditions in the params hash.

# So I had some Ruby code like this:

@items = MyActiveRecordClass
@items = @items.some_scope_method if some_condition?
@items = @items.another_scope_method
@items = @items.yet_another_scope_method if some_other_condition?
@items = @items.one_more_scope_method
@items = @items.the_fifth_scope_method if some_condition?

# But I did not like that as it was so repetitive and so I was thinking about
# using Object#tap and clean this mess up:

@items = MyActiveRecordClass.tap do |items|
  items.some_scope_method if some_condition?
  items.another_scope_method
  items.yet_another_scope_method if some_other_condition?
  items.one_more_scope_method
  items.the_fifth_scope_method if some_condition?
end

# .. but turns out that I am a moron and scopes don't mutate the receiver but
# return a new object instead, so this is not going to work. Fail.
