Very cool!

I can see how this would be annoying to write. But as a reader, I
really prefer it! If all the variables were called "builder", I would
be confused. Much easier if I know exactly which builder you are
referring to -- especially since the declaration -- "builder -> { ..."
-- often starts near the right margin.

Your Big.java provides an excellent example why this rule is great! :)
