The building blocks of Lua are functions. All functions can be referenced, 
where you cannot make a reference to an arbitrary statement. A chunk is just a 
specific type of function: one which is generated from a complete pass of the 
parser over an input source. (Not necessarily a file or string, since the 
load() function can accept a function as a source.)

The significance of a chunk, compared to a regular function, is that a chunk 
is not created in the context of another function. This is relevant to where 
global variables come from.
