No, on the virtual implementation (only inside of my brain), they are
same things.  The magic is in receiving and interpreting arguments.

No, we don't have to.  The colon can be ugly with symbols, for
example, 

  db.find(order: :date)

is not good looking.  Any other proposal (except for "=')?

Unfortunately, assignments are legal in argument list in Ruby.
