 Which hacks are these? Also, I don't see how it's different from
 =C2=B4"foo".tap{|s|s<<"bar"}=C2=B4

 Can you give some examples?

----------------------------------------
After a discussion in our team chat today, I wondered if it would be a good=
 idea to have a version of String.new that accepts a block and works as a s=
tring builder. Something like

    string =3D String.new("foo") do |s|
      s << "bar"
    end
    string #=3D> "foobar"

If the argument is omitted an empty string would be passed to the block ins=
tead.

That could be a nice solution to avoid all the Array#join and "".tap hacks =
for string creation.
