it's because they get merged without explicit calls. that's really the
only reason.
btw: first class values are values that can be passed as an argument,
returned as a value, and stored in a data structure. in perl only scalars
are first class thus you must reference every value with a scalar to use
them in the mentioned places. (accept maybe with prototypes you can pass
them, i'm not sure)
