Does the Lua grammar help?

"stat" is a statement.  "exp" is an _expression_.

http://www.lua.org/manual/5.3/manual.html#9

Note: There is some overlap.  Some statements also happen to be
expressions (and vice versa).

For example:  "x" is an _expression_ (it expresses a value).  "x = 5" is
a statement.  "foo ()" is both.

The load function turns a chunk into a function.
