Comparison: Integers

Integer literals

reveal_type(1 == 1 == True)  # revealed: Literal[True]
reveal_type(1 == 1 == 2 == 4)  # revealed: Literal[False]
reveal_type(False < True <= 2 < 3 != 6)  # revealed: Literal[True]
reveal_type(1 < 1)  # revealed: Literal[False]
reveal_type(1 > 1)  # revealed: Literal[False]
reveal_type(1 is 1)  # revealed: bool
reveal_type(1 is not 1)  # revealed: bool
reveal_type(1 is 2)  # revealed: Literal[False]
reveal_type(1 is not 7)  # revealed: Literal[True]
reveal_type(1 <= "" and 0 < 1)  # revealed: @Todo | Literal[True]

Integer instance
