In Lua, assignment is actually *not* a true expression operator. It's
only a statement, which is why you can't do things like "a = b = c =
1", or "while ((a = a + 1) < 10)" like you can in other, more C-based
languages. My understanding is that keeping this strict division
between expression and statement is part of the simplicity that Lua
needs to keep its parser as fast as possible.
