# Shows the definition of a compound trait.

#--[Example*]-------------------------------------------------------------------

# Create a sample Die:
die = Die()

# Try out some sample valid values:
die.value = 3
die.value = 'three'
die.value = 5
die.value = 'five'

# Now try out some invalid values:
try:
    die.value = 0

try:
