Programming in Lua The Lua Implementation

•Lua keeps the implementation simple by maitaining a linked list of open upvalues, and searching this list each time it needs to create a closure •If no open upvalue for a variable is found, Lua creates one and adds it to the list •When an upvalue is closed it is removed from the list •Each time a block goes out of scope the Lua compiler generates code to close any open upvalues in it
