If the code consists of nothing but expressions (which yours does), you can write:

(RiWorldBegin())
(   RiColor(1.0,1.0,1.0))
(   RiSurface('constant'))
(   RiSphere(1.0,-1.0,1.0,360))
(RiWorldEnd())

or

(
RiWorldBegin(),
    RiColor(1.0,1.0,1.0),
    RiSurface('constant'),
    RiSphere(1.0,-1.0,1.0,360),
RiWorldEnd()
)
