Derp, I misread.

Kinda.

Lua defines it implicitly only when you use the

function foo:bar(a, b, c) -- note the colon

syntactic sugar, which gets translated to

function foo.bar(self, a, b, c) -- note the period

In all cases, self is a regular variable name. You can even redeclare a new local with that name even when the old one is in scope.

Edit: some typos

if debug.getinfo(1).what == "main" then
  -- ...
end

Not that you’ll ever use it. No, seriously.

Edit: actually, they are not quite equivalent. This code just checks whether we are outside any function, not necessarily in the main file (i.e. not in a module). I don’t think there’s an equivalent to Python’s __name__ in stock Lua.
