Variable types

SGScript has 10 primary variable types:

• null: the 'lack of a better value' type
• bool: boolean, true/false
• int: signed integer
• real: floating point number
• string: byte buffer
• (SGS) function: function that was defined in and compiled from SGScript code
• C function: function defined in C code
• object: the extension type and container for complex built-in types
• ptr: the pointer type
• thread: the context/thread/coroutine type

Extended variable types (built on object):

• array: a dynamically allocated variable array
• dict: a map/table structure where variables are mapped to string keys
• map: a map/table structure where variables are mapped to variable keys
• class: object that uses two other objects to build its interface
• closure: a callable object consisting of another callable and several variables
• event: an object that allows to stop a thread
