# Both single and multiple assignment is supported

# Whole array
x = ["a", "b", "c"]
print "x = [1, 2, 3] gives: ", x, "\n"

# just the first element
x, = ["a", "b", "c"]
print "x, = [1, 2, 3] gives: ", x, "\n"

# multiple to n vars
x, y, z = ["a", "b", "c"]
print "x, y, z = [1, 2, 3] gives: ", x, ", ", y, ", ", z, "\n"

# We can use star params with that. The starred param gets the remainder
x, *y = ["a", "b", "c"]
print "x, *y = [1, 2, 3] gives: ", x, ", ", y, "\n"

# Leading from this, we can see that Ruby supports multiple assignment.
# Multiple assignment works in parallel, such that we can swap arguments
# like so:
puts "x = #{x}; y = #{y}"
x, y = y, x
puts "x = #{x}; y = #{y}"

# It's handy for any kind of initialization
x, y = 13, 'etc'
puts "x = #{x}; y = #{y}"
