# C++ style definition of enum symbol types:
enum Bool
{
	False,
	True
}


io.writeln( Bool::False )
io.writeln( Bool.True )


switch( Bool.False ){
case Bool::False : io.writeln( "Bool::False" )
case Bool::True  : io.writeln( "Bool::True" )
}

# The following will also work without casting,
# but it will be less efficient:
switch( (Bool) $True ){
case Bool::False : io.writeln( "Bool::False" )
case Bool::True  : io.writeln( "Bool::True" )
}


# Symbols can be assigned to a variable of an 
# enum symbol type, as long as they are compatible:
var bl : Bool = $True
io.writeln( bl )


# The following is equivalent to:
# enum CardSuit { Club, Diamond, Heart, Spade }
type CardSuit = enum<Club,Diamond,Heart,Spade>

var card : CardSuit = $Spade
card = CardSuit::Spade

# In the following switch-case, the case constants $XYZ
# can also be replaced with CardSuit::XYZ. Both will be
# compiled into a jumping table, because the types of
# "card" and switch case constants can be known/inferred
# at compiling time:
switch( card ){
case $Club:    io.writeln( "Club card" )
case $Diamond: io.writeln( "Diamond card" )
case $Heart:   io.writeln( "Heart card" )
case $Spade:   io.writeln( "Spade card" )
}
