Not as clear, and more error prone than
    field := soccer_schedule.location;
Not to mention that "field" could be of type "soccer_field_ids" in Ada,
thus allowing the compiler to check that you aren't assigning the hour of
the game to the variable "field", rather than of type "Unsigned_96" which
prevents the compiler from helping you guard against error.
