Object yielders

object.rb

class Object
  def then_maybe
    yield(self) || self
  end

  def then_if(condition)
    condition ? yield(self) : self
  end

  def then_unless(condition)
    !condition ? yield(self) : self
  end
end

Just realized then_if could potentially also be when, e.g. Record.all.when(bar) { _1.where(foo: bar) }, unless it's a keyword.

🤔 The only thing is when might sound like we’re doing an equality comparison against self, e.g.

def when(comparator)
  if ==(comparator) || is_a?(comparator)
    yield(self)
  else
    self
  end
end

This would make sense if we don’t know in advance what we’re calling when on but we want to yield the block if it matches a condition.

I was thinking of it as a blank case statement like:

case
when condition then yield(self)
end

But true, it can be confusing.
