Added 'any' atom

[GolfingSuccess]

Ẹ would behave like Ạ but for any instead of all.

Test cases:

• [] -> 0
• [0] -> 0
• [0, 0, 0, [0], 0, 0] -> 1
• [1, 500, -1] -> 1
• [0, 0, [], 0] -> 1 (?)

I just merged your PR to update the "unused letters for single atoms". Could you remove Ẹ as well.

Also, why would [0, 0, [], 0] yield 1?

[GolfingSuccess]

sorry for being late, but I removed Ẹ as well, and yes [0, 0, [], 0] should return 1 (untested) to keep up with Ạ's behavior

[DennisMitchell]

[0, 0, [], 0] returns 0 as it should, as all elements of the array are falsy.
