Clozure CL (often called CCL for short) is a free Common Lisp implementation
with a long history. Some distinguishing features of the implementation include
fast compilation speed, native threads, a precise, generational, compacting
garbage collector, and a convenient foreign-function interface.

Intel machines have both 32-bit and 64-bit versions available. ARM machines
currently only have a 32-bit version available. 64-bit for ARM is in
development.

Tested as working on Samsung Chromebook Plus (ARMv8).
