Infinite Loops

In Lua.

Lawful

Good

A classic.

while true do
	-- body
end

Neutral

A different take on it.

repeat
	-- body
until false

Evil

Remember tail call optimizations.

local function loop()
	-- body
	return loop()
end
loop()

You don't even need the local variable given the powerful debug library:

(function() --[[body]] return debug.getinfo(1).func() end)()

Alternatively (who needs spaces?):

while-1do
	-- body
end

Chaotic

Good

Back to the future!

::loop::
-- body
goto loop

Neutral

A short infinite for iterator.

for _ in (function return true end) do
	-- body
end

Thanks to ywang for some golfing.

Evil

Numeric for plus some double magic.

for _ = -1e308, 1e308, 1e-308 do
	-- body
end

Shorter variant by ywang:

for _ = math.huge, math.huge do
	-- body
end

Instead of using math.huge, you can also divide something nonzero by zero.
