    x:RVaQaVR:x

Takes input as a command-line argument; outputs `1` for palindrome, `0` for non-palindrome. [Try it online!]

The core of what we want to do is `RVaQa`: `reverse(a) string-equals a`. The code `x:RVaQa` calculates this result and assigns it to `x`. Then `VR:x` assigns the value of `x` to the variable `VR`. Since this assignment is the last statement in the program, its value is also autoprinted. Voila!

For a previous interesting version using some undefined behavior, see the revision history.
