Many familiar shapes can be generated by sweeping simpler ones through
space and considering the resulting path, surface, or volume.
Sketch implements this idea in the sweep command.
def n_segs 8
sweep { n_segs, rotate(180 / n_segs, (0,0,0), [0,0,1]) } (1,0,0)
This code sweeps the point (1,0,0)
eight times by rotating it
180/8 = 22.5 degrees each time and connecting the resulting
points with line segments. The def used here is a
scalar definition.

scalars have no enclosing brackets at all.
