I was perhaps overly strict in my criticism. The call to setrlimit is sensible
as it is a different way of assigning a known value (20 megabytes... except
the lower-case 'm' irks me very slightly) to a known something-like-an-lvalue,
which is a value in the kernel.
The confusion I was thinking of is where an assignment statement does
something that is not in any way like an assignment. For example, I wouldn't
be comfortable using a HTTP library like this:
local connection = http.new()
connection.get = "http://www.lua.org/"; -- send a request
html.parse(connection.get) -- read result
