Examples
From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.
d = dict(["a", "b"], [1, 2])
d = set(d, "c", 3)
print(get(d, "b")) # 2
print(keys(d)) # ("a", "b", "c")
print(values(d)) # (1, 2, 3)
print(items(d)) # (("a", 1), ("b", 2), ("c", 3))
print(has_key(d, "c")) # true
print(has_key(d, "z")) # false
