c = colour
c.red = 0; c.blue = 255; c.green = 0
del c # Not strictly needed, but limits the scope of c

When everything's a reference, the Pascal 'with' syntax doesn't gain
you anything over a single-letter variable name. As I recall, it's
handy in Pascal because record assignment has value semantics rather
than reference semantics.
