Re: assignments in expressions?

["Steve Williams" <stevewilliams@...>]

Why the need to do that?  That leads to hard-to-read code that is no more
efficient than a easier to understand layout.  Are we going to have an
Obfuscated Lua Code Contest?

What is wrong with this way?  It is no different in functionality and easier
to understand.

c = f()
while c == 1 do
  print(c)
  c = f()
end
