Type System

• : the unit type, usually for representing missing values.
• bool: the boolean type.
• : a 64 bit floating point type.
• char: a C-like unsigned char type, 0-255.
• : a heterogeneous array, 0-indexed (unlike in Lua).
• dict: a heterogeneous hash map.
• : a special error type, to ease distinction of errors from other values. This type can only be instantiated by the built-in std.error function.
