Hy On Earth
Hy is a Dialect (computing), dialect of the Lisp (programming language), Lisp programming language designed to interact with Python (programming language), Python by translating s-expressions into Python's abstract syntax tree (AST). Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte. Lisp allows operating on code as data (metaprogramming), thus Hy can be used to write domain-specific languages. Similar to Kawa (Scheme implementation), Kawa's and Clojure's mappings onto the Java virtual machine (JVM), Hy is meant to operate as a transparent Lisp front-end for Python. It allows Python Library (computing), libraries, including the standard library, to be imported and accessed alongside Hy code with a Compiler, compilingThe term "compiled" may apply to expressing Hy code in Python's AST or converting that AST into bytecode, the latter being dependent on the specific Python interpreter used and not Hy. step where both languages are converted into Python's AST.Hy ...

Cuttlefish
Cuttlefish or cuttles are marine molluscs of the order Sepiida. They belong to the class Cephalopoda which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone, which is used for control of buoyancy. Cuttlefish have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. They generally range in size from , with the largest species, the giant cuttlefish (''Sepia apama''), reaching in mantle length and over in mass. Cuttlefish eat small molluscs, crabs, shrimp, fish, octopus, worms, and other cuttlefish. Their predators include dolphins, sharks, fish, seals, seabirds, and other cuttlefish. The typical life expectancy of a cuttlefish is about 1–2 years. Studies are said to indicate cuttlefish to be among the most intelligent invertebrates.
