**Explanation:**

<!-- language-all: lang-python -->

 ι # Uninterleave the (implicit) input-list of characters
 # i.e. ["t","t","t","t","e","e","s","s","t","t","!","!","!"]
 # → [["t","t","e","s","t","!","!"],["t","t","e","s","t","!"]]
 Ë # Check if both inner lists are equal
 # → 0 (falsey)
 # (after which the result is output implicitly)
