Parentheses

The title of this article is not correct because of technical limitations. The correct title is actually ().

() is an esolang that is impossible to interpret

syntax	function
((x)	increment the variable inside
(x))	decrement the variable inside
((x)(y)z)	if x=y do Z
((x))	declares new variable x
(x(y))	sets x to y
()	halts the program when ran
((x	input ascii into x as binary { ( is 1 ) is 0}
x))	output x as ascii
(((x)))	repeats x infinitely

now let's create an example program

((x)) (x(())) ((x)(x)x)

this program will halt.
